Item 10.5

EMERGENCY STOP SIGNAL

Modified as Following.

Warning

The safety machine should be designed based on the evaluation results of machine risk

assessment. Use the emergency stop signal properly in order to design the safety machine.

To configure an emergency stop circuit in compliance with the safety standards of IEC60204-1 in

which requirements for electrical components of machine are specified, observe the following

cautions. IEC60204-1 specifies that an emergency stop circuit shall function as a category 0 or 1

stop.

Category 0 stop:

Stopping by immediate removal of power to the machine actuators (Uncontrolled stop)

Category 1 stop:

A controlled stop with power to the machine actuators available to achieve the stop and then

removal of power when the stop is achieved

(Controlled stop)

Fig. 10.5(a) or Fig. 10.5(b) or Fig. 10.5(c) shows an example showing how to make connections for

the emergency stop signal with this CNC controller and servo amplifier (αi series or βi series or

βi SVSP) to comply with the EU Machine Instructions. Fig. 10.5(d) shows a flow diagram of the

emergency stop circuit signals.

The emergency stop signal is input to the Safety relay module. The output signal from the relay is

input to the CNC controller and Power Supply (PS). The Power Supply outputs control signal for a

motor power magnetic contactor, which can be used to switch the power applied to the Power

Supply on and off. An emergency stop signal is usually generated by closing the B contact of a

pushbutton switch.

When the emergency stop signal (*ESP) contact is closed, the CNC controller enters the emergency

stop released state, such that the servo and spindle motors can be controlled and operated.

When the emergency stop signal (*ESP) contact opens, the CNC controller enters the emergency

stop state, and the servo and spindle motors stop. In case of Fig. 10.5(a) or 10.5(b) or 10.5(c), the

spindle motor power is shut off after the spindle motor is decelerated to a stop (Category 1 stop).

Meanwhile, the servo motor is forced to be a dynamic stop as a rule (Category 0 stop). By setting

relevant parameter, however, it is also possible to decelerate the servo motor to a stop, and then to

shut off the servo motor power (Category 1 stop).

Regarding how the Spindle motor or the Servo motor stops when the emergency stop button is

pushed, refer to the Item 10.3 and the Item 10.4. Regarding specifications of parameters related in

these matters, refer to the FANUC AC SERVO parameters manual(B-65270JA).

The example of the emergency stop signal circuit showed in Fig.10.5(a) or Fig. 10.5(b) or Fig.

10.5(c) complies with the requirements of the safety standard ISO13849-1, Performance Level(PL)

c or d. However, when calculating PL value concretely, the calculation should be based on the

safety standard ISO13849-1 with the reliability data provided by each parts supplier. In case for

the reliability data of CNC, please contact FANUC sales office.

CAUTION

1 This CNC controller can detect overtravel by using a software limit function. If the software limit

function does not operate effectively due to a failure, resulting in a possible serious accident or

loss, install a safety circuit, for example, a stroke end limit switch arranged in series with the

emergency stop button.

2 To use a spindle motor and amplifier produced by a manufacturer other than FANUC, refer to

the corresponding documentation as well as this manual. Design the emergency stop

sequence such that, if the emergency stop signal contact opens while the spindle motor is

rotating, the spindle motor is decelerated until it stops.

G.11 PARAMETER SETTING

(1) At emergency stop, turn on the power of CNC.

(2) Follow the procedure below to set parameters concerned with FSSB.

In the case of using Analog servo adapter, the FSSB automatic setting function is not available. It is

necessary to set the value of No.1023, No.1815, No.1905, No.14340 to14357, No.14376 to 14391 and

No.1936 to 1937 in the manual setting No.2 mode. Refer to “FSSB setting” of the connection manual

(function edition) about the detail of the setting.

When this parameter is set, Analog servo adapter is basically treated in the similar way to the separate

type detector interface unit. (After this, Analog servo adapter and the separate type detector interface unit

are called “an interface unit”.)

Follow the explanation below and the Parameter Manual (B-64310EN) of CNC and set the appropriate

value.

The analog servo amplifier is numbered as if it was connected from the terminal slave (the

most far slave from CNC). Each one-axis analog servo amplifier is numbered one slave

number. For example, if the terminal unit connected to FSSB is slave 5, the analog servo

amplifiers are numbered from 6. (Refer to the example described later.)

This parameter is set as follows.

In case of amplifier (including analog amplifier):

Set a value obtained by subtracting 1 from the setting of parameter No.1023 for the axis

to which the amplifier is assigned.

1 The protection function is intended to protect the components internal to the modules

rather than external units.

2 No protection function of modules can protect their internal components in all cases.

Once any protection function has worked, remove the cause promptly. If an absolute

maximum rating is exceeded, for example, it is likely that protection functions may not

work or an IC may break down before the related protection function works, depending

on the way or situation in which the modules are used.

9.11.6.2 DO alarm detection

States when the protection function is activated in extension module C

CAUTION

1 If the overheat protection function or over voltage protection function among the

protection functions above is activated, the DO bit is kept OFF until the cause is

eliminated. When the cause is eliminated, the DO bit is set to ON without restarting

the system.

2 Disconnection detection is performed by monitoring, with an output element in the

module, the current flowing through a load when DO output is ON. When the detected

current value is about 200 mA or less, disconnection detection is assumed. So, when

a device (such as an LED) with a small load current is connected, the DO alarm state

results, assuming disconnection detection. Unlike the other protection functions,

however, this function does not turn off DO output. If a connection is reactivated after

the state of disconnection is once set, disconnection detection is canceled without

restarting the system.

3 When the ratings current value of the load is larger than the disconnection detection

current value, and the rise time of the current that flows to the connected load (such

as an solenoid) is late, the disconnection detection function might work. For that

case, the disconnection detecting function when DO output is ON can be evaded by

programming it to refer to DO alarm allocated to DI after the fixed time has passed

since DO was turned on.

WARNING

The output voltage of SVC pin is not valid when ENB is turned off (ENB1 and 2 are

unconnected). For example, although the spindle command voltage is 0V when

S0 is specified, the output voltage of SVC pin is not precisely 0V because of noise

and error contained in the output voltage. So ENB is turned off whenever S0 is

specified.

The output voltage of SVC pin is not valid when a system alarm occurs or

immediately after turning on/off the power of the control unit. In such cases, ENB

is turned off. Therefore the spindle motor should not be activated while the ENB is

off.

Failures in the control units and the analog spindle amplifier as well as input power

abnormality and communication failures can hamper the normal operation of

these units. Design the system in such a way that the machine can operate safely,

for example, by providing an external safety circuit so that no accident will occur

even if the system fail to operate normally.

As stated previously, ENB is designed in such a way that, if a system alarm occurs

or the power of the control unit is turned off, ENB is turned off. However it is not

guaranteed that ENB is surely turned off. So it is required that an external safety

circuit must be configured to ensure the safety, regardless of the state of ENB.

NOTE

1 The output rating of ENB1 and ENB2 is 200mA /30V.

2 The analog output ratings are as follows;

Output voltage: ±10V

Output current: 2mA (MAX)

Output impedance: 100 ohm

3 The parenthesized pins are used for the high-speed skip function (HDI). Don’t

connect to non-assigned pins.

4 The connector specification “FI80-20P,DF1R020WB1” is used with the

LCD-mounted type control unit. “PCR-EV20MDT” is used with the stand-alone

type control unit.

5 The recommended cable connector FI30-20S (manufactured by Hirose Electric)

cannot be used for the stand-alone type control unit in following combination.

5 The +5V signals above can be used to feed power to the detectors. The supply

current is 0.35 A maximum.

The position coder generates rectangular wave voltage signals in proportion to the angle of rotation of the

spindle, and is used in feed per revolution and thread cutting.

The figure below shows the timing of the signals generated by the pulse coder.

NOTE

The differential signal is used as the feedback signal from the position coder.

*PCA, *PCB and *PCZ refer to each of their inverted signals.

Time rules

These are the signal rules that apply to the input pin of the input connector of the control unit in the figure

above.

Because the signal of this connector is in phases A and B and is a differential input, Td is of interest, which

is the duration from point A when the relative potential difference between PCA and *PCA becomes 0.5V

or higher to point B when the relative potential difference between PCB and *PCB reduces below 0.5V. Its

minimum is:

Td ≥ 0.65μs

Tp, which is the minimum of one period in each of phases A and B, is:

Tp ≥ 4μs

Tw, which is the minimum of the phase Z siginal (one-rotation signal) width, is:

Tw ≥ One period of the phase A or B signal

Time rules for digital encoder

The encoder has two types of analog and digital. Digital type encoder outputs A,B and Z phase signals

synchronized to internal clock of the encoder and Td is always longer than regulated value. In contrast, the

period of A, B and Z phase signals of analog type encoder may be as short as possible depending on the

revolution of the encoder.

In the digital type encoder, because the timing between Z and A or B signal can be defined, the following

time rule can be applied. Time rules for A and B phase signals are same as above.

Tw ≥ 1/2 period of the phase A or B signal

(In this regard, Tj, which is phase difference between phase A or B signal and phase Z signal, should

be within 100ns)

WARNING

The maximum rotation speed of the position coder can be determined in

accordance with these timing rules. However, even if the rotational speed of the

position coder is lower than the maximum rotational speed, if Td not met the timing

rule because of the spindle axis vibration so on CNC can not receive the signals

from the position coder and it may cause the missing of the spindle position.

Input voltage requirements

The voltage of the A and B phase signals must meet the following requirements:

High level: 2.4 V or more

Low level: 0.8 V or less

The relative potential difference of A, B and Z phase signal should be 0.5V or more.
