The Number Of Power Modules Detected (11.071) is different from the number expected. The sub-trip value indicates the number of power modules expected.

Recommended actions:

Ensure that all the power modules are correctly connected and powered up.

Ensure that the value in Number Of Power Modules Detected (11.071) is set to the number of power modules connected.

Set Number Of Power Modules Test (11.035) to 0 to disable the trip if not required.

This trip is also initiated if the number of external rectifiers connected to each power module is less than the number defined by Number Of Rectifiers Expected

(11.096). If this is the reason for the trip the sub-trip is 10x where x is the number of external rectifiers that should be connected.

Recommended actions:

Ensure that all the external rectifiers are connected correctly.

Ensure that the value in Number Of Rectifiers Expected (11.096) is correct.

Trip

Control Word

Value

Short description

This trip is initiated by setting bit 12 on the control word in Control Word (06.042) when the control word is enabled (Control Word Enable (06.043) = On).

Recommended actions:

Check the value of Control Word (06.042).

Disable the control word in Control Word Enable (06.043).

Trip

Current Offset

Value

225

Short description

The current feedback offset is too large to be trimmed correctly. The sub-trip relates to the output phase for which the offset error has been detected.

Sub-trip

Recommended actions:

Ensure that there is no possibility of current flowing in the output phase of the drive when the drive is not enabled.

Hardware fault - contact the supplier of the drive.

Trip

Data Changing

Value

Short description

A user action or a file system write is active that is changing the drive parameters and the drive has become active, i.e. Drive Active (10.002) = 1. The user actions

that change drive parameters are loading defaults, changing drive mode, or transferring data from an NV memory card or a position feedback device to the drive.

The file system actions that will cause this trip to be initiated if the drive is enabled during the transfer are writing a parameter or macro file to the drive, or

transferring a derivative or user program to the drive. It should be noted that none of these actions can be started if the drive is active, and so the trip only occurs if

the action is started and then the drive is enabled.

Recommended actions:

Ensure the drive is not enabled when one of the following is being carried out:

Loading defaults

Changing drive mode

Transferring data from a NV media card or position feedback device

Transferring user programs

Trip

Derivative ID

Value

247

Short description

There is a problem with the identifier associated with derivative image which customises the drive. The reason for the trip is given by the sub-trip as follows.

Sub-trip

Reason for trip

There should be a derivative image in the product but this has been erased.

The identifer is out of range.

The derivative image has been changed.
