PTP Profile

Each PTP device has a set of attributes as define by IEEE1588-2008. On the inverter the default attributes values are set as follows. Note that
some may be modified by a parameter.

Attribute

Description

Inverter default value

Modified by parameter

domainNumber

A domain consists of one or more PTP devices
communicating with each other. Devices on the
same domain will have the same domain number.

1787 PTP Domain Number

slaveOnly

When

slaveOnly

is TRUE the PTP device may only

be a slave and not become a master clock.

FALSE

1684 PTP Clock Type

logAnnounceInterval

A port in the MASTER state will periodically transmit
an Announce message.
Announce messages will be transmitted such that the
logarithm to the base 2 of the mean value of the
interval in seconds between message transmissions
is the value of the

logAnnounceInterval

1
(2 seconds)

logSyncInterval

A port in the MASTER state will periodically transmit
a Sync message.
Sync messages will be transmitted such that the
logarithm to the base 2 of the mean value of the
interval in seconds between message transmissions
is the value of the

logSyncInterval

-1
(0.5 seconds)

1681 PTP Log Sync Interval

logMinDelayReqInterval

The

logMinDelayReqInterval

will specify the

minimum permitted mean time interval between
successive Delay_Req messages.
This value is determined and advertised by a master
clock based on the ability of the master clock to
process the Delay_Req message traffic.

announceReceiptTimeout

The value of

announceReceiptTimeout

will specify

the number of announceInterval that has to pass
without receipt of an Announce message

Fire Mode

13-1

Chapter 13:

Fire Mode

Caution

When Fire Mode is active the Drive and Motor protection trips are disabled. The use of Fire Mode itself increases the risk of causing a fire by

overloading the drive or motor, so it must only be used after assessing the risks.

Intended Use

Fire mode is intended for use in critical situations where it is imperative for the motor to be kept running if at all possible. In such a situation it may be

reasonable to override the drive’s normal protective functions. An example of a critical situation may be a ventilation fan in a stairwell, where

continued operation in the event of a fire may assist the safe evacuation of personnel.

Summary

When Fire Mode is enabled the drive firmware attempts to keep the drive running wherever possible. If the drive was running when Fire Mode was

activated it will continue to run. If the drive was stopped when Fire Mode was activated then the Fire Mode firmware will attempt to start it. While Fire

Mode is enabled the majority of trips will be ignored, (possibly leading to damage to the drive, motor or attached equipment). If one of the remaining

enabled trips does occur then the Fire Mode firmware will wait until the trip source has become inactive and will then restart the drive.
When Fire Mode is deactivated the drive will return to its previous sequencing mode. If the drive was running in Local mode the motor will be

stopped. If the drive was running in remote terminals or remote communications mode the drive will continue running according to the relevant

control word, (refer to Appendix B).

Configuration

The parameters used to configure Fire Mode are detailed in Appendix D. This description is partially duplicated here for convenience.

PNO*

Parameter Descriptions

Activate

A Boolean input. Set to TRUE to enable Fire Mode according to the Fire Mode parameter. This input parameter may only be set by

connection to a digital input.
Default value FALSE

1961*

Setpoint

A reference value to be used when Fire Mode is active. Setting a negative setpoint will cause the drive to rotate in reverse direction.
Default value 0.0%. Range -100% to 100%

1962*

Level

An enumerated input parameter. Selects the mode of operation when Fire Mode is enabled

0. DISABLED

1. PARTIAL

2. FULL

Default value is DISABLED.

1963*

Restart Delay

Specifies the time to wait before attempting to reset a trip.

1964*

Activated

A Boolean output that indicates when Fire Mode is active. This is TRUE when

Level

is either PARTIAL or FULL, the

Setpoint

is not

0.0% and

Activate

is TRUE.

1965*

Enabled

A Boolean output that indicates when Fire Mode will be activated if

Activate

is set TRUE. This is TRUE when

Level

is either

PARTIAL or FULL and the

Setpoint

is not 0.0%.

1966*

Last Activated

A Data and Time output parameter that records the last time that the fire mode became active. This may be used to validate that

the fire mode has been tested. This value is recorded in non-volatile memory. The value will be reset if an application is loaded that

does not implement Fire Mode.

1967*

Activation Count

An integer output parameter that records the number of times the fire mode has become active. This value is saved in non-volatile

memory. The activation count will be reset if an application is loaded that does not implement Fire Mode.



These PNO values are correct for the Fan Application. Custom configurations may assign the Fire Mode parameter to different PNOs.

Fire Mode

13-3

Functional Description

When Fire Mode is enabled the normal speed reference and start / stop control of the drive are modified.

Sequencing

Sequencing is the term given to controlling when the drive runs. When Fire Mode is enabled the normal sequencing control signals are over-ridden.

The parameters that control this are

PNO 0610

Sequencing::App Control Word bit 0, Switch On, (refer to Appendix B:Sequencing Logic). In typical applications bit 0 of the App

Control Word is driven from a digital input, used as a Coast Stop signal.

Level

is set to DISABLED or

Setpoint

is zero then setting

Activate

to TRUE will have no effect.

Level

is set to either PARTIAL or FULL and

Setpoint

is not zero then setting

Activate

to TRUE will activate Fire Mode. When Fire Mode is active

the drive will run, (turn the motor).

The only reasons that the drive will not run are:



Level

is changed back to DISABLED



Activate

is changed back to FALSE



Setpoint

is change to zero



The Coast Stop input is activated.



The STO circuit is activated.



An enabled trip source becomes active.



A hardware fault

Reference

The Fire Mode

Setpoint

parameter is selected automatically whenever Fire Mode is

Activated

. The Setpoint is passed through the System Ramp,

(see Appendix D).

Caution

Fire Mode does not override the standard Ramp features. Specifically

0497 Ramp Hold

can prevent the setpoint changing to

the Fire Mode

Setpoint

value.

SAFE TORQUE OFF

Note 1. The Under Voltage trip is enabled when Fire Mode is active, but the trip level is reduced by 50%.

If a trip source becomes active when the associated trip is disabled the drive will continue to run. This is also the normal behavior of the drive, (when

Fire Mode is not active). If the associated trip is designed for drive protection, this will be recorded in non-volatile memory. The recorded values are

available to view in the Trips History parameter block, (refer to Appendix D).

When Fire Mode is activated and a trip source becomes active and the associated trip is enabled, the drive will trip, causing the motor to stop. This

is similar to the normal behavior of the drive, (when Fire Mode is not active). However, when Fire Mode is active the drive firmware continues to

monitor the trip source, once the trip source has become inactive the drive automatically resets the trip condition and restarts the drive.

The Fly catching feature can be used to allow the drive to smoothly resume control of a moving load on restart.

Motor Control Modes

The operation of Fire Mode is independent of the motor type motor and the control mode, (Open Loop or Sensorless Vector control).

Modbus TCP

INTRODUCTION

The inverters built-in Ethernet includes a Modbus TCP server. The Modbus registers are mapped to the inverters parameters. Up to 3
simultaneous connections to Modbus clients are possible. TCP port 502 is used.

Making a connection to the Ethernet and setting an IP address on the inverter is described in Chapter 12 (Ethernet). If the Modbus TCP is used
as part of a process control it is recommended a dedicated network be used with fixed IP addresses for the inverter.

To allow Modbus TCP connections to the inverter, the parameter

0939 Maximum Connections

must be set to a value greater than zero.

Modbus Register Mapping Summary

The inverter parameters are mapped to the Holding Registers and Input Registers, either as a fixed mapping or as a user-defined mapping.
There is no mapping to Coils or Discrete Inputs.

Holding Register Address

00529 - onwards

Fixed mapping to the inverter parameter values.

Fieldbuses

A-2

FIXED PARAMETER MAPPING

Each parameter number is mapped onto

two

consecutive Modbus registers regardless of the parameter data type. The relationship between the

Holding Register or Input Register is given as:

Register number = (parameter number - 1) * 2 + 529

•

If the parameter has a data type that uses one byte then it will occupy the low byte of the first register and the high byte will be zero, i.e. the
register will not be sign extended.

•

If the parameter has a data type that uses two bytes then it will occupy the first register.

•

Unused register locations will read zero; writing to that location will have no effect.

•

The word order of 32-bit parameters is determined by the inverter parameter

0940 High Word First

•

Writable 32-bit parameters will only accept a change in value if

both

registers mapped to the parameter are written to in the same request.

Fixed Parameter Mapping - Arrays

Some parameters have multiple elements and are classified as parameter arrays. A parameter array has a parameter number that represents
the

whole

of the array, but also has parameter numbers that represent each

element

of the array. An example is given below.

Array Example

A parameter array called

Recent Trips

has 10 elements.

Parameter Number

Parameter – Recent Trips

895

Whole array

896

index 0

897

index 1

905

index 9

If the parameter number of the whole array is 895, then the parameter number of the element index 0 of the array will be 896, the parameter
number of the element index 1 will be 897, etc.

Note:

String

array parameters access their elements via parameter numbers that are calculated in a different way (see Fixed Parameter Mapping

- Strings).

Accessing the parameter arrays via the parameter number that represents the whole array is not recommended. This will access only the first
four bytes (2 registers) of the array. The array should rather be accessed via its elements.

A-3

Fieldbuses

Fixed Parameter Mapping - Strings

Strings parameters have a parameter number that represents the whole string. This parameter number is mapped to two registers so limits
access to the first four characters. Additional contiguous parameter numbers are set aside so that the whole string can be accessed: one
additional parameter number for each four characters. The strings are packed into the registers

low byte first

String Example

A string parameter called

My String

has a string length of 12 characters (plus the null terminator). This will have one parameter number allocated

for the whole string (in this example 161) and 3 further parameter numbers for the string fragments (162-164).

If the value of the string is “0123456789AB”:

“89AB”

00855

‘9’

‘8’

00856

‘B’

‘A’

Note: This is example is not a real parameter.

As each inverter parameter maps to two registers, if the registers that represent the whole string are accessed then only the first four characters
will appear. To access the whole string over Modbus use the registers that map to the parameter number of the whole array plus one, in this
example

0162

(register

00851

). A multiple read or write of registers will then provide access to the whole string.

A-4

String Array Example

A string array parameter called

My String Array

has 2 elements of string length 5 characters (plus the null terminator) each. In this example the

parameter number of the whole array is 175.

then parameter number
