Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The test software is not working correctly, or the actual
hardware is faulty.
Recommended actions
Perform a shutdown and then restart the controller. If the
problem persists, isolate the faulty drive unit and replace it.
39421, Drive Unit configuration test failure
Description
Drive unit number arg in drive module arg has detected an
internal error.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The connection to the drive unit may be bad or incorrect
hardware may have been fitted.
Recommended actions
Perform a shutdown and then restart the controller. If the
problem persists, isolate the faulty drive unit and replace it.
39422, Drive Unit watchdog timeout
Description
The time limit for watchdog timer for drive unit number arg in
drive module arg has expired.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The connection to the drive unit may be bad or incorrect
hardware may have been fitted. It may also be caused by an
internal error in the drive unit.
Recommended actions
Perform a shutdown and then restart the controller. If the
problem persists, isolate the faulty drive unit and replace it.

Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
There may be problems with the control cable, the DC link
connection (bus bar or cable) or internal hardware.
Recommended actions
Check the control cables and DC link connection (bus bar or
cable) are correctly inserted for this unit. Restart the controller.
39424, Drive Unit internal error
Description
Internal measurement warning for drive unit number arg in drive
module arg.
Supervision Code = arg.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The connection to the drive unit may be bad or incorrect
hardware may have been fitted. It may also be caused by faulty
control cable, DC link connection (bus bar or cable) or internal
hardware.
Recommended actions
Make sure the control cables and DC link connection (bus bar
or cable) are correctly connected for this unit. Perform a
shutdown and then restart the controller. If the problem persists,
isolate the faulty unit and replace it.
39425, Drive Unit measurement failure
Description
A current measurement circuit in drive unit number arg, drive
module arg, attached to joint arg has failed.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
This may be caused by a faulty or lacking DC link connection
between the rectifier and drive units.
Recommended actions
Make sure the DC link connection (bus bar or cable) is correctly
connected between the rectifier and drive unit. Check the
indication LEDs on the rectifier and drive units. The significance
of the LEDs is described in the Trouble Shooting Manual.
