Safety instructions for line reactors

Note

When using a line reactor, also observe the safety instructions in Section 1.

WARNING

Danger to life due to high voltages on the additional winding of the HFD line reactor

If system oscillations do occur and no damping resistor is connected, impermissibly high

voltages may arise on the additional winding of the HFD line reactor.

• Connect a damping resistor to the HFD line reactor.

CAUTION

Risk of burns due to high surface temperatures

The line reactors can become very hot. You can get seriously burnt when touching the

surface.

• Mount the line reactors so that contact is not possible. If this is not possible, attach

clearly visible and understandable warning notices at hazardous positions.

• To prevent adjacent components from suffering damage due to these high

temperatures, maintain a clearance of 100 mm on all sides of the line reactors.

NOTICE

Damage or destruction of components

Unsuitable line reactors can cause damage/faults on Line Modules. Line harmonics can

also occur that damage/disturb loads connected to the same line supply.

• Only use line reactors or Active Interface Modules described in this manual.

Note

Malfunctions through magnetic fields

Reactors produce magnetic fields that can disturb or damage components and cables.

• Arrange the components and cables at a suitable distance (at least 200 mm) or shield the

magnetic fields appropriately.

Line connection

6.6 Line reactors

Note

Keep the connection cables as short as possible

The connection cables between line reactor and Line Module, as well as between line

reactor and line filter, must be kept as short as possible (max. 10 m).

You must use shielded connection cables, whose cable shields are attached at both ends.

Shielding can only be omitted if the following conditions are met:

• The cables do not exceed 1 m in length.

• The cables are laid flush with the rear metal wall of the control cabinet.

• The cables are laid in a way that keeps them physically separate from signal cables.

Do not route any cables near the line reactor. If this cannot be avoided, observe a minimum

distance of 200 mm.

6.6.2

HFD line reactors for Active Line Module

6.6.2.1

Description

HFD line reactors are used in older systems for connecting regulated infeed/regenerative

feedback components (Active Line Modules) to the network.

They perform the following functions:

● Limiting of low-frequency line reactions

● Energy store for the step-up operation of the infeed units

● Current limiting for line supply oscillations

● Together with a damping resistor, the HFD line reactors as an HFD package dampen the

system oscillations of the converter system.

The HFD line reactor should be mounted as close as possible to the line supply infeed

component.

Note

In newer systems, Active Interface Modules are usually used in place of HFD packages (see

the chapter titled Active Interface Module (AIM) (Page 129)

DC link

7.1

Function of the DC link

Properties

Line Modules generate a DC voltage from the three-phase line voltage, and feed this into the

DC link. The DC link is used as a source of energy, which supplies DC voltage to the Motor

Modules (inverters). There are DC link components which buffer energy or dissipate excess

energy in order to stabilize the energy supply.

DC link busbars or DC link adapters are used for voltage transfer within the DC link.

7.2

DC link components

The information below provides only a brief explanation of the DC link components. For more

detailed information, refer to the SINAMICS S120 Booksize Power Units Equipment Manual.

Note

Safety instructions in the Booksize Power Units Equipment Manual

Observe the safety instructions for DC link components in the SINAMICS S120 Booksize

Power Units Equipment Manual.

Note

Information on the Control Supply Module (CSM)

You can find information on the Control Supply Module in the chapter titled Internal power

DC link

7.2 DC link components

7.2.1

Braking Module

The Braking Module Booksize is always used together with an external braking resistor. It

has the following tasks:

● Specific stop of the drives in the event of a line failure

(e.g. emergency retraction or EMERGENCY OFF category 1).

● Limit the DC link voltage for brief periods of generator operation (e.g. if the regenerative

feedback capability of the Line Module is deactivated or is not adequately dimensioned).

● Convert braking energy into thermal energy if a Line Module without regenerative

feedback capability (BLM) is being used.

The Braking Module includes the necessary power electronics and control. When the

Braking Module is in operation, the energy which is fed back into the DC link is dissipated via

an external braking resistor.

External braking resistors

Braking resistors without thermostatic switch 6SN1113-1AA00-0DA0 (PN = 0.3 kW) and

6SL3100-1BE31-0AA0 (PN = 1.5 kW) can be operated at the Braking Module Booksize.

The cable lengths between the Braking Module and braking resistor is limited to a maximum

of 10 m.

The scope of delivery of the braking resistor 6SN1113-1AA00-0DA0 includes a shielded

connection cable (3 m, 3 x 1.5 mm²).

Rapid discharge of DC link capacitors

Furthermore, the Braking Module Booksize can used with a braking resistor to quickly

discharge the DC link capacitors The DC link is discharged in a controlled manner via the

braking resistor once the infeed unit has been switched off and the line-up has been

disconnected from the line supply (e.g. via the main switch or line contactor). The function

can be activated via a digital input on the braking module. A quick discharge makes sense,

for example, when maintenance tasks are to be performed at the Motor Module and/or motor

installation (reduction of the discharge time).

CAUTION

Rapid discharge only when motors are at a standstill

The drive system must be completely disconnected from the line supply in order for rapid

discharge to take place. The motors must be at a standstill.

Monitoring functions

● Automatic detection of braking resistors and braking power monitoring

● I²t monitoring of the braking resistors.

● Temperature monitoring of the Braking Module

● Short circuit and overload detection

● Ground fault detection

DC link

7.3 Current Carrying Capacity of the DC Link Busbar

7.2.2

Capacitor Module

Capacitor Modules are used for making energy savings, particularly in multi-axis systems.

They store the energy supplied to the DC link in such a way that it is neither dissipated as

heat loss nor returned to the line system in a way that is subject to losses. If the energy

requirements of the connected Motor Modules increase, the energy is removed from storage.

Only when this energy store is fully charged is the additional excess energy dissipated as

heat loss via a braking resistor.

Due to its storage capacity the Capacitor Module can also bridge short-term power failures.

Capacitor modules function autonomously. It is connected to the DC link voltage via the

integrated DC link busbars.

Several capacitor modules can be operated in parallel.

7.3

Current Carrying Capacity of the DC Link Busbar

The current carrying capacity of the DC link busbar must be observed for the configuring and

the construction of the drive group.

Depending on the width of the power units, the maximum current carrying capacity of the DC

link busbar is represented by the following values:

● With power units between 3 A and 30 A (max. width 100 mm) and DC link components

(Braking, Capacitor, and Control Supply Modules), the DC link busbar can be loaded with

100 A

● With power units between 45 A and 200 A (150/300 mm width), the DC link busbar can

be loaded with 200 A

DC link busbar gain

Gain is possible as an option. It may be required if the drive group is fed via a Line Module >

55 kW or a DC link adapter.

Using reinforced DC link busbars raises the current-carrying capacity from 100 A to 150 A for

all booksize components with widths of 50 mm or 100 mm.

DC link

7.3 Current Carrying Capacity of the DC Link Busbar

Optimizing current load

The current in the DC link busbar is directly dependent on the current active power of the

motor. To calculate the current generated, the entire process operation associated with the

drive group connected to the DC link needs to be considered. The current load for the DC

link busbar can be optimized if influencing variables such as partial load, duty cycles, and the

simultaneity factors of the individual drive motors are taken into account.

If the current carrying capacity of the DC link busbar is exceeded, two solutions are possible:

either the building of the drive group with infeed from left and right (center infeed; see below)

or the use of another Line Module.

Note

The following examples are based on the concurrent use and loading of the Motor Modules

with the rated output current of the Motor Modules. The current values are taken from the

Booksize Power Units Equipment Manual or the NC62 catalog.

Example 1:

Connection of several Motor Modules with different current carrying capacity of the DC link

busbar to a Line Module.

Note

A center infeed with Motor Modules to the right and left of the Line Module can be configured

7.4 DC link rectifier adapter

7.4

DC link rectifier adapter

The DC link rectifier adapter supplies the DC link voltage directly. It is best used for

supplying an individual component. With a direct supply, each component is connected to

the DC link separately. The internal DC link busbar is not used here.

If the DC link rectifier adapter is to be used for supplying more than one component, it is

important to remember that it can only be installed on the component on the far right. The

choice of connection cable diameter should be based on the required summation current for

all the connected components.

The connection cables must be fused accordingly.

Mounting on components with reinforced DC link busbars is not possible.

Note

When a DC link rectifier adapter and DC busbars are used, the limit values for radio

interference suppression under Category C2 according to EN 61800-3 can no longer be

observed.

Electronics Power Supply

For the electronics power supply, a differentiation is made between:

● external power supply with SITOP modular

● internal power supply with Control Supply Module (CSM)

8.1.1

External power supply (SITOP)

An external SITOP modular power supply must be provided for the electronics power supply

of the individual SINAMICS components. This ensures the trouble-free operation of all

SINAMICS components. The SITOP electronics power supply also has the advantage that

the power supply is already equipped with an internal line filter (class B in accordance with

EN55022). This ensures an EMC-conform operation.

If a power supply other than SITOP is used, the required rated data (see Equipment Manual

for Booksize Power Units) must be observed to ensure a trouble-free operation.

24 VDC power is required to supply

● the electronics of the SINAMICS components using the integrated 24 V busbar

● the electronics for Control Units, Option Boards and Sensor Modules, and the process

voltage of their digital inputs

● the load voltage of the digital outputs

● the motor holding brakes

Other consumers may be connected to the power supply devices provided they have

separate protection against excess current.

CAUTION

If other consumers are connected to the power supply, switch inductances (contactors,

relays) must be provided with suitable over-voltage protective circuits.

The operation of motors with integrated holding brake requires a regulated DC power supply.

The power is supplied from the internal 24 V busbars. The voltage tolerances of the motor

holding brakes and the voltage losses of the connection cables must be observed.

8.1 Electronics Power Supply

The DC power supply should be set to 26 V. The Control Supply Module supplies 26 V. This

following general conditions are satisfied:

● Use of Siemens three-phase motors

● Use of Siemens MOTION-CONNECT power cables

● Motor cable lengths maximum 100 m

The following conditions should be considered for the configuring:

● The line infeed of the power supply devices must be tapped in front of the line filter of the

Line Module.

● The line connection of the power supply should be made directly and without additional

switched feeders.

● The dimensioning of the output rated current of the power supply is determined by the

load of the connected consumers.

● A load reserve should be provided; a utilization of 0.7 to 0.8 IN is recommended.

● The total length (sum of all cables) of the supply cables for the 24 VDC electronics power

supply between the power supply and the SINAMICS components must not exceed

10 meters.

● The connection cable does not need to be shielded nor twisted. The maximum value of

the ripple voltage, however, must not be exceeded. If this is the case, appropriate

measures must be adopted.

● Where possible, the additional supply for consumers exterior to the SINAMICS system,

such as contactors, valves, etc., should come from a separate power supply. This

reduces any interactions (voltage dips, etc.).

For Smart/Active Line Module, Motor Module and for the NX component, the supply voltage

is monitored by the system. The components are connected using DRIVE-CLiQ; the

monitoring is performed in the Control Unit.

Connection via 24 V terminal adapter

The component's front cover will need to be opened before establishing a 24 V connection to

a module in booksize format. This exposes other live components, such as DC link busbars.

DANGER

Risk of electric shock

A hazardous DC link voltage is present for up to 5 minutes after the power supply has been

switched off.

The protective cover may only be opened after this time has elapsed.

When opening the protective cover for the DC link, you must press the release catch. A

suitable tool (e.g. screwdriver or supplied unlocking tool) must be used for this purpose.

An integrated 24 VDC busbar is used for the electronic power supply of the

Line/Motor/Braking and Capacitor Modules. The current carrying capacity of this busbar is

max. 20 A. The integrated busbar also supplies the motor brake control terminals of the

Motor Modules.

The infeed of the electronic power supply is normally made directly on the Line Module using

the 24 V terminal adapter (max. connectable cross-section 6 mm², max. fuse 20 A) supplied

with the Line Modules.

Connection of the components in SINAMICS drive system

8.1 Electronics Power Supply

The 24 V busbar is used to pass the 24 VDC power between the individual components.

24 V jumper plugs (supplied with the Line Modules) are used to jumper the 24 V busbar at

the component transitions.

If the maximum current carrying capacity (20 A ) of the 24 V busbar is exceeded, an

additional electronic current infeed must be provided. This must be implemented, for

example, on a Motor Module using an additional 24 V terminal adapter, which must be

ordered separately (order no. 6SL3162-2AA00-0AA0). The 24 V busbar must not be

jumpered upstream of the new infeed, because a new potential begins downstream of the

additional infeed.

Jumper plugs

Figure 8-2

Electronic power supply infed more than once

For all other components, such as Control Unit or Sensor Module, the electronic power

supply is connected using appropriate infeed plugs at the associated component. The infeed

plugs are identical for all components. The maximum connectable cross-section is 2.5 mm²

and the maximum current carrying capacity is 20 A.

To improve the wiring of the individual components with each other, a potential jumpering at

the infeed plugs is possible. The total current of all attached components, however, must not

exceed 20 A.

Power is supplied to the digital inputs/outputs at the Control Unit and Sensor Module, for

example, via appropriate terminals (max. 0.5 mm²).

8.1.1.5

Overcurrent protection

On the primary side and on the secondary side of the power supply device, devices and

cables must be protected from over-current using suitable protection devices.

Primary side

Recommended circuit-breakers (IEC 898) in the suppy cable can be found in the technical

data of the SITOP devices in the KT 10.1 catalog. The cable cross-section must be

considered.

The primary protection is responsible for providing device protection for the SITOP power

supply as well as line protection between the protective device and the power supply.

Secondary side

For the protection of the secondary side, particular attention must be paid to:

● Loading due to loads, possibly the simultaneity factor in response to machine operation

● The current carrying capacity of the cables in normal operation and in a short-circuit

situation

● The ambient temperature

● The effect of bundling together cables, e.g. where these are laid in a common duct

● Cable laying method to EN 60204-1

EN 60204-1, Section 14, can be used to determine the overcurrent protection devices.

Protection of the load feeders

Load feeders must be protected selectively. Circuit-breakers are suitable (order no.: 5S…,

ETB1 catalog) or the SITOP select diagnostic component (order no.: 6EP1961-2BA.0).

Configuration details for the secondary protection of the load feeders are contained in the KT

10.1 catalog (SITOP Power Supplies, "Technical Information and Configuration Notes"

section).

The rated size of the protective devices depends on the current need. The protective device

also performs the line protection and sometimes also the device protection of the attached

consumers. In a fault situation, the used power supply must be able to supply the required

power until being controlled.

Regulated power supplies (such as SITOP power) must be provided, in accordance with EN

60204-1, with integrated electronic short-circuit protection capable of independently

protecting SITOP power and the supplied 24 VDC circuits against overloading in the event of

overloads/short circuits.

Circuit-breakers

When selecting circuit breakers from the table below, the following cable conditions need to

● Ambient temperature 40 °C or 55 °C

● Max. 1 conductor pair bunched

● Conductor limit temperature 70 °C for normal operation

● Maximum cable length:

10 m for the supply cables

30 m for signal lines

● To be laid separately from other cables and conductors carrying operating current

● Cable type: PVC conductor cable

The MCBs can be selected according to Siemens catalog "BETA Modular Installation

Devices - ET B1".

8.1.1.6

Line formation

The corresponding different supply lines should be configured and constructed depending on

the size of the drive group and the overall length. This ensures that should one line fail, the

power supply to all attached consumers does not fail. The fault-free consumer lines remain

operational.

The maximum connectable cross-section of the consumers must also be considered:

●

6.0 mm² for the 24 V power supply terminal adapter of the power busbar

●

2.5 mm² for the 24 V power supply infeed terminal of the CU and SMC components

●

0.5 mm² for the digital inputs/outputs and analog inputs/outputs

Connection of the components in SINAMICS drive system

8.1 Electronics Power Supply

Example for the splitting of the consumer lines:

● NCU / NX

● Line / Motor Modules

● Supply of the Sensor Modules

● Consumers such as relays, valves, etc.

● Additional brakes not supplied from the Motor Module

Multiple power supplies are recommended for larger plant concepts.

Example of the separation:

● Power supply for the direct drive system (NCU, NX, LM, MM, SME and SMC)

● Power supply for additional consumers, such as brakes, valves and power contactors

If required, the circuit-breakers can be equipped with additional auxiliary switches. If these

signal contacts are fed to a higher-level controller, a detailed fault diagnosis can be

performed when the circuit-breakers trip.

Notes

● SINAMICS components have a reverse polarity protection on the 24 VDC infeed side.

● Line, Motor, Braking, Capacitor and Control Supply Modules are short-circuit resistant on

the 24 V busbar for a maximum current of 20 A. The 24 V terminal adapter for the infeed

has a maximum connection cross-section of 6 mm².

● If no higher short-circuit current can occur, a protection can be omitted. This means the

components can be connected directly to the power supply.

● If higher short-circuit current occur, a protection against over-current / short-circuit must

be provided, max. 20 A, however. In a fault situation, the used power supply must be able

to supply the required current until tripping.

● The maximum protection of the power supply infeed for Control Unit and Sensor Module

Cabinet depends on the connected cable cross-section (max. 2.5 mm²), maximum 20 A,

however.

● The maximum protection of the controller inputs/outputs at the other components

depends on the connected cable cross-section:

8.1.2

Internal power supply via the Control Supply Module (CSM)

The Control Supply Module (CSM) is a 24 VDC power supply unit integrated as a separate

SINAMICS component in the drive line-up. It provides an output voltage of 24 VDC - 28.8

VDC. This can be adjusted using an integrated potentiometer.

The CSM supplies all SINAMICS components in the drive line-up and also components,

such as Control Unit or Sensor Module Cabinet with 24 VDC. The maximum output current is

20 A DC. An external power supply is not essential.

In normal operation, the Control Supply Module is supplied from the line voltage. In the event

of a power failure, the module automatically changes over to supply from the DC link.

Depending on the energy content in the DC link, the CSM can maintain the supply of the 24

V busbar. This allows transient line fluctuations to be bridged without the drive line-up failing.

To achieve longer bridging times, additional Capacitor Modules can be used to increase the

DC link capacity. The consequent increased storage capacity of the DC link acts positively

should the line voltage drop.

Specific emergency return movements, such as those required in the machine tool area, can

also be initiated. This is necessary, for example, to stop rapidly rotating spindles as fast as

possible or to protect expensive workpieces by making appropriate return movements of the

axes. Further measures, however, must be considered for the realization.

The Control Supply Module has safe electrical separation between the line potential and the

DC link potential. This therefore ensures that the DC link is not unintentionally charged. The

Control Supply Module can therefore remain connected to the supply if the Line Module is

galvanically isolated from the supply, for example via a line contactor.

The 24 V ground of the Control Supply Module is internally grounded.

The Control Supply Module is cooled using an internal fan.

Temperature and voltages are internally monitored.

Temperature monitoring:

In the event of an overtemperature in the Control Supply Module, a temperature advance

warning is issued via a signaling contact. If the temperature falls below the limit value within

the advance warning time, then the module remains operational and the signaling contact is

de-energized. If the overtemperature condition persists, the module is switched off and

restarted.

Voltage monitoring:

When the monitoring threshold (32 V) of the output voltage is exceeded for more than 20 ms,

the Control Supply Module switches off and attempts a restart after 10 s. This is

supplemented by a hardware-based overvoltage limiting. This prevents that more than 35 V

can be output in the case of a fault.

The Control Supply Module can be operated individually or as part of a parallel connection of

up to ten Control Supply Modules. The switchover between single and parallel operation is

realized in a no-current state using a DIP switch on the upper side of the module.

Compatibility

The new Control Supply Module 6SL3100-1DE22-0AA1 with extended functions described

here replaces Control Supply Module 6SL3100-1DE22-0AA0. The modules are spare-part-

compatible.

CSM in the event of line failure

When planning the line failure concepts, those components located outside the SINAMICS

drive line-up must also be considered (line contactor, controller, etc.). If, in the event of a

fault, the primary energy supply of the CSM comes from the DC link, this can be performed

only in the voltage range UDC link = 430 - 882 VDC (300 - 430 VDC for < 1 min). If these limits

are overshot or undershot, the corresponding error messages will be generated by the

system and internal pulse suppression will be triggered. The drives coast to a standstill and

can no longer be controlled. To limit the maximum/minimum DC link voltage, the use of

Capacitor and Braking Modules may be necessary.

Note

The supply voltage corresponds to PELV (protective extra-low voltage). The required

connection of the ground potential to the protective conductor system is realized in the CSM.

Note

Safety instructions and other information

You can find detailed information on the Control Supply Module in the SINAMICS S120

It is absolutely essential that you follow the safety instructions listed there.

Connection of the components in SINAMICS drive system

8.1 Electronics Power Supply

8.1.2.1

Connection

The Control Supply Module is connected to the line supply (3-ph. 380 VAC -10 % to 480

VAC +10 %) via interface X1 (screw terminals 0.2 to 4 mm ²) This connection should

preferably be made without using an isolating device (e.g. a contactor).

The CSM has an internal line filter (Class A for TN systems) and the pre-charging circuit for

the DC link inside the unit, from which the isolated 24 V supply is generated.

The CSM also features a current limitation function. When using cables with a cross-section

of 2.5 mm², no additional protection is required on the 24 V side if a type XLPE or EPR cable

is used, or a cable with a similar quality and with thermal stability of up to 90 °C.

Note

Observe the connection sequence

If a selectively tripping, AC/DC-sensitive RCCB is used for the drive line-up, the Control

Supply Module must always be connected to the line supply downstream of this circuit

breaker. Otherwise, the residual current operated circuit breaker will trip erroneously if the

direct-current component is asymmetrically withdrawn in certain operating states.

Parallel operation

A maximum of 10 Control Supply Modules can be connected in parallel.

The DIP switch of the Control supply Module must be set to "parallel mode". The same

output voltage must be set for all modules at the adjusting potentiometer.

In parallel mode, each Control Supply Module should supply the 24 VDC voltage via the 24

V terminal adapter. For this reason, the red 24 V connector must not be used (see

connection examples).

Use of a SITOP redundancy module (6EP1961-3BA20) is recommended for parallel

connection. One SITOP redundancy module must be used for two Control Supply Modules

in this case. Alternatively, a connection with external diodes to decouple the individual

Control Supply Modules is possible. If a Control Supply Module fails, an alarm is generated

and provided via the X21 signaling contact. The 24 V supply is maintained via the second

module.

Note

Only Control Supply Modules with order number 6SL3100-1DE22-0AA1 may be used for

parallel connection.

Introduction

The Line Module is used to connect the drive group to the energy supply system.

The Line Module is used for the power infeed into the DC link.

In generator operation, the energy of the drives fed into the DC link is returned to the energy

supply system. For an energy supply system that cannot accept any regenerative energy

(e.g. diesel generator), the regenerative capability of the Line Module must be deactivated.

The braking energy must then be converted into heat via a Braking Module with braking

resistor that also needs to be included in the drive group.

Line Modules can be directly connected to TN and TT systems, both with grounded neutral

point and grounded line conductor; they can also be connected to IT systems. Line Modules

have an integrated overvoltage protection function.

Active Line Module

The self-managed infeed/regenerative unit with booth converter creates an increased

controlled DC link voltage. This makes the connected Motor Modules independent of

tolerances in the energy supply system.

The Control Unit is used to control, trigger and monitor the Active Line Module. Data

exchange is performed via the DRIVE-CLiQ interface.

Control types:

The Active Line Module operates in two different control types depending on the

parameterized line voltage (p0210).

● Active Mode

The Active Line Module can control the DC link voltage in a rated voltage range of 3 AC

380 V to 3 AC 415 V (input voltage); boost converter with controlled DC link voltage and

sinusoidal line voltage.

● Smart Mode

In the rated voltage range of 3 AC 416 V to 3 AC 480 V (input voltage), Smart Mode is

automatically activated and the supply system transistors are switched so that they are

synchronous with the supply system. The DC link voltage is not regulated, but is based

on the rectified line voltage according to the following formula: UDC link = Usupply * 1.35.

The setpoint for the DC link voltage (p3510) will be preassigned automatically.

to select Active Mode if the connected motors are suitable for > 650 VDC.

Note

Observe the insulation voltage

The setpoint for the DC link voltage (p3510) can be changed. The insulation voltage of the

motors must be observed. (See the NC62 catalog or the Configuration Manual for the

motors.)

CAUTION

Dangerous voltage at the DC link

As soon as the energy supply is present at the infeed terminals (-X1:U1/V1/W1) of the

Active Line Module, the DC link will be precharged (UDC link = USupply x 1.35).

Once the "Enable Pulses" enabling signal is also present at the Active Line Module, the

boost converter increases the DC link to the specified setpoint p3510 (e.g. UDC link = 600 V

for Usupply = 400 V).

Smart Line Module

The Smart Line Module is a non-regulated infeed/regenerative feedback unit. The

regenerative capability can be deactivated using a digital input.

The DC link is supplied using an uncontrolled diode bridge. The size of the DC link voltage is

based on the line voltage according to the following formula: UDC link = Usupply * 1.35.

The following DC link values are achieved for the Smart Line Module:

For the 5/10 kW types, control and monitoring of the Smart Line Module is carried out

exclusively via digital inputs/outputs. No connection to the Control Unit using DRIVE-CLiQ

exists.

Basic Line Module

The Basic Line Module can only feed energy from the supply system into the DC link; energy

cannot be fed back into the supply system. Therefore, this module is only suitable for

applications in which there is no regenerative energy, or in which the energy exchange takes

place between the motor-driven and generator-driven axes in the DC link.

Safety instructions for Line Modules Booksize

Note

When using a Line Module Booksize, it is imperative that you observe the safety instructions

in Section 1.

DANGER

Danger to life through electric shock as well as fire hazard due to overcurrent protective

devices that trip too late

Overcurrent protective devices that do not trip or trip too late can cause an electric shock or

fire.

• To protect personnel and for fire protection purposes, at the infeed point, the short-

circuit rating and loop impedance must correspond to the specifications in the

documentation in order that the installed overcurrent protection devices trip within the

specified time.

DANGER

Danger to life through electric shock due to a high DC link voltage

As long as the Line Module is connected to the line supply, the DC link is charged with a

high voltage. Contact with components can result in death or serious injury.

• Isolate the Line Module from the line supply during installation or maintenance work,

e.g. via the line contactor or main switch.

DANGER

Danger to life through electric shock due to the residual charge of the DC link capacitors

Because of the DC link capacitors, a hazardous voltage is present for up to five minutes

after the power supply has been switched off.

Contact with live parts can result in death or serious injury.

• Do not open the protective cover of the DC link until five minutes have elapsed.

• Measure the voltage before starting work on the DCP and DCN DC link terminals.

DANGER

Danger to life through electric shock when the protective cover of the DC link is open

Contact with live parts can result in death or serious injury.

• Only operate the components with closed protective cover.

WARNING

Danger to life through interruption of the external protective conductor due to high leakage

currents

The drive components conduct a high leakage current via the protective conductor.

Touching conductive parts when the protective conductor is interrupted can result in death

or serious injury.

• Ensure that the external protective conductor satisfies at least one of the following

conditions:

- It has been laid so that it is protected against mechanical damage. ¹⁾

- If it is a single cable, it has a cross-section of at least 10 mm² Cu.

- If it is a conductor of a multi-conductor cable, it has a cross-section of at least 2.5

mm² Cu.

- It has a second protective conductor in parallel with the same cross-section.

- It complies with the local regulations for equipment with increased leakage current.

¹⁾ Cables laid within control cabinets or closed machine housings are considered to be

adequately protected against mechanical damage.

WARNING

Danger to life through electric shock due to incorrect connection to the DC link

Incorrect connections can lead to overheating and therefore a risk of fire. There is also a

risk of an electric shock. This can result in serious injury or death.

• Only use adapters (DC link adapters and DC link rectifier adapters) released by

Siemens for the connection to the DC link.

WARNING

Danger to life through electric shock due to incorrectly installed DC link bridges

Incorrectly installed DC link bridges at the left-hand end of the drive line-up can cause an

electric shock.

• For all 50 mm wide modules (exception: Smart Line Modules), remove the DC link

bridge, including the screws. Do not tighten the screws without the DC link bridges.

• For all components that are 75 mm wide or wider, the DC link bridges must not be

moved to the left or removed.

WARNING

Danger to life through electric shock due to missing DC link side covers

There is a danger of an electric shock through contact when the side covers of the DC link

are missing.

• Mount the side covers on the first and last component in the drive line-up.

You can order missing side covers (order number: 6SL3162-5AA00-0AA0).

WARNING

Danger of an accident due to missing warning labels in the national language.

Missing warning labels in the national language can result in death or serious injury.

• Attach the component warning labels in the national language.

WARNING

Fire hazard due to overheating because of inadequate ventilation clearances

Inadequate ventilation clearances can cause overheating with a risk for personnel through

smoke development and fire. This can also result in more downtimes and reduced service

lives of Line Modules.

• Maintain the 80 mm clearances above and below the Line Modules.

• For the 80 kW and 120 kW Active Line Modules, a ventilation clearance of 50 mm must

also be maintained in front of the fan.

CAUTION

Fire hazard due to overheating when the total length of the power cables is exceeded

Overheating and a fire can result when the total length of the power cables is exceeded.

• Ensure that the total length of the power cables (motor supply cables and DC link

cables) does not exceed the values specified in Section "Possible line reactor and line

filter combinations".

NOTICE

Material damage due to loose power connections

Insufficient tightening torques or vibrations can result in faulty electrical connections. This

can cause fire damage or malfunctions.

• Tighten all power connections with the specified tightening torques, e.g. line supply

connection, motor connection, DC link connections.

• Check the tightening torques of all power connections at regular intervals and tighten

them when required. This applies in particular after transport.

NOTICE

Damage to the equipment when performing a voltage test as a result of connections that

are not disconnected

As part of routine tests, SINAMICS S components undergo a voltage test according to EN

NOTICE

Damage to the equipment due to excess energy not being fed back to non-regenerative

supply systems

Excess energy that is not fed back can damage equipment.

• For line supplies without regenerative feedback capability (e.g. diesel generator),

deactivate the regenerative feedback capability of the Active Line Modules and Smart

Line Modules via parameter p3533.

• The braking energy must then be dissipated via an additional Braking Module with

braking resistor in the drive line-up.

Exception: For 5 kW and 10 kW Smart Line Modules, the regenerative feedback capability

must be deactivated as follows:

• Jumper between terminals X22.1 and X22.2

• Ground at X22.4

NOTICE

Damage to external loads when using a disconnector unit without prior voltage interruption

For Line Modules with regenerative feedback capability, switching off a running drive line-

up with a disconnector unit can destroy external loads that remain on the same switching

component parallel to the drive.

• Therefore, interrupt the voltage first at terminals X21.3 (EP +24 V) and X21.4 (EP M).

This can be achieved using a leading breaking auxiliary contact (≥ 10 ms), for example.

NOTICE

Damage through use of incorrect DRIVE-CLiQ cables

Damage or malfunctions can occur on the devices or system when incorrect or unreleased

DRIVE-CLiQ cables are used.

• Only use suitable DRIVE-CLiQ cables that have been released by Siemens for the

respective application.

Note

Malfunctions due to polluted DRIVE-CLiQ interfaces

Malfunctions can occur in the system through the use of polluted DRIVE-CLiQ interfaces.

• Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.

Special features for Line Modules with external air cooling

NOTICE

Component failure due to the pollution of external heat sinks

For components with external air cooling, the fan and the heat sinks can accumulate a lot of

pollution. If the cooling air requirement is not provided by the filtered fan, the components

cannot output their specified power. This can cause the temperature monitoring function in

the components to respond.

• Check the fans and heat sinks for pollution at regular intervals and clean them when

necessary.

Note

Checking the seal

• After installation, check the seal on the rear of the device to ensure that it is tight.

• If required, use additional sealing.

Note

Using an installation frame

• Only use an installation frame when the cabinet has an unpainted metal surface.

Note

The Active Line Module (16 kW, 36 kW) and the Smart Line Module (16 kW, 36 kW)

interfaces are identical.

Active Line Modules with internal air cooling

8.3.3.1

Description

Active Line Modules generate a constant, regulated DC voltage in the DC link from the three-

phase line supply voltage that supplies the connected Motor Modules with power.

This ensures that they are not influenced by network fluctuations.

When the motors are in feedback mode, Active Line Modules supply power back to the

network. The regenerative feedback capability of the modules can be deactivated by

parameterization.

The DC link starts precharging as soon as the supply voltage is applied and is independent

of its phase sequence direction. Load can be applied to the DC link after the modules have

been enabled. An optional main contactor is required for disconnecting the voltage.

Active Line Modules can be directly connected to TN and TT line supplies - both with

grounded neutral point and also with grounded protective conductor; they can also be

connected to IT line supplies. The Line Modules have an integrated overvoltage protection

function.

WARNING

Danger to life due to charged DC link

For operation, the 24 VDC voltage must be connected to terminal 3 and ground to terminal

4. When withdrawn, pulse suppression is activated. Regenerative feedback is deactivated

and the bypass relay drops out. If the Line Module is not disconnected from the supply

system when the EP terminal is deactivated (e.g. a line contactor is not installed), the DC

link remains charged.

Note

If an active drive line-up is switched off by means of the disconnector unit, the voltage at

terminals 3 (EP +24 V) and 4 (EP M) must be interrupted beforehand. This can be carried

out using a leading (≥ 10 ms) breaking auxiliary contact, for example.

This protects external loads located parallel to the drive on the same switching component.

DANGER

Risk of electric shock!

Only temperature sensors that meet the safety isolation specifications contained in

EN 61800-5-1 may be connected to terminals "+Temp" and "-Temp". If safe electrical

separation cannot be guaranteed (for linear motors or third-party motors, for example), a

Sensor Module External (SME120 or SME125) or Terminal Module TM120 must be used.

If these instructions are not complied with, there is a risk of electric shock!
