5 Troubleshooting by event log
5.5 3 xxxx
Continued
Consequences
The system goes to system failure state.
Probable causes
The integrity check of the drive unit information stored on the
drive unit has failed.
Recommended actions
Retry again by restarting the controller using the main power
switch. Replace the faulty drive unit.
34409, Drive unit startup error
Description
The system has failed to complete the initialization phase of a
drive unit. The drive unit is located in drive module arg at unit
position arg.
Consequences
The system goes to system failure state.
Probable causes
The system has failed to complete the initialization phase of
the drive unit.
Recommended actions
Retry by restarting the controller using the main power switch.
Check for other hardware event log messages.
34410, Too many drive units connected
Description
In drive module arg the system has detected more drive units
than the system can handle. The maximum number of drive
units supported is arg, but arg was detected.
Consequences
No operation will be possible until the fault is corrected. The
system goes to system failure state.
Probable causes
Too many drive unit that are connected.
Recommended actions
Disconnect unused drive unit(s).
34411, DC link error
Description
The system has detected an unexpected low DC bus voltage
in a drive unit that is not used by any joints. The drive unit is
located in drive module arg at unit position arg.

Consequences
No operation will be possible until the fault is corrected. The
system goes to Motors Off state.
Probable causes
Incoming mains are missing. The DC bus cable is faulty
connected to the drive unit. Short circuit on a DC bus. It can be
both inside the drive unit and in the cables.
Recommended actions
Check incoming mains. Check DC cabling. Check if there are
any short circuit. Replace the drive unit(s).
34423, Incompatible drive unit types
Description
The configured drive system in drive module arg contains
incompatible drive unit types.
Consequences
The system goes to system failure state.
Probable causes
Drive units of type DSQC462 are not compatible with any other
drive unit types and may not be used in the same drive module.
Recommended actions
Check the configuration to make sure that only compatible drive
unit types are use within the same drive module.
37001, Motors ON contactor activation error
Description
Motors ON contactor arg in drive module arg failed to close
when ordered.
Consequences
The mechanical unit cannot be run manually or automatically.
Probable causes
The run chain for the contactor is open. There are problems in
the contactor itself, either mechanical or electrical. The
FlexPendant enabling device may have been toggled too
quickly, or the system may not be configured correctly. On rare
occasions, this fault may occur in combination with other faults,
in which case this may be found in the error log.
Recommended actions
To resume normal operation, first acknowledge the error, then
release the enabling device and press it again after approx.
one second. Check cables and connections on the safety
system. Check any other error log messages coinciding in time
with this one for clues. Check the system motion configuration
regarding Motors ON relay. How to check the configuration file
