34262, Incoming mains frequency warning
Description
In drive module arg, the incoming mains voltage has wrong
frequency. The rectifier unit at drive unit position arg has
reported the problem.
Consequences
The system may stop with DC link voltage too low.
Probable causes
The incoming mains frequency is not within specification. Short
circuit between motor phases or ground.
Recommended actions
Check and adjust incoming mains frequency. Check the motor
cable and motor by measuring their resistance respectively.
Disconnect before measuring.
34263, Rectifier startup error
Description
In drive module arg, the dc-link in the rectifier unit at drive unit
position arg has too low voltage.
Consequences
No operation will be possible until the fault is corrected. The
system goes to Motors Off state.
Probable causes
Low AC-voltage level to rectifier input. This may be caused by
a faulty rectifier inrush control resistor. A short circuit is present
on the dc-link.
Recommended actions
Restart the controller and try again. Check incoming mains
voltage. Check all internal 3-phase components (main switch,
mains filter, fuse, contactors) and cabling in the drive module.
If new installed system with mains transformer - check
transformer voltage selection. If drive unit has additional axes
- check dc-link wiring. If the problem remains then replace the
unit.
34264, Rectifier inrush limitation active in Motors
On
Description
In drive module arg, the inrush control resistor in the rectifier
unit at drive unit position arg is wrongly engaged.
Consequences
The system goes to Motors Off state to protect the hardware.
Operating manual - Troubleshooting IRC5
3HAC020738-001 Revision: AA
Probable causes
This error occur when the DC link voltage becomes too low and
all mains phases are missing.
Recommended actions
Check the hardware event log for other errors. Check incoming
mains voltage. Check that the correct voltage is selected with
jumpers on the transformer (optional). Check all internal 3-phase
components (main switch, mains filter, fuse, contactors) and
cabling in the drive module.
34265, DC link short circuit error
Description
In drive module arg, the DC link in the rectifier unit at drive unit
position arg is short circuit.
Consequences
No operation will be possible until the fault is corrected. The
system goes to Motors Off state.
Probable causes
DC link cables for an additional drive unit is damaged or wrongly
connected. Internal error in rectifier unit or drive unit.
Recommended actions
Check DC link cables and connectors.
34266, Rectifier inrush limitation and bleeder
active
Description
In drive module arg, with rectifier unit at drive unit position arg,
the inrush control resistor is active at the same time as the
bleeder resistor is active.
The inrush control resistor is located in the rectifier unit.
The bleeder resistor is connected to the rectifier unit or the
drive unit with embedded rectifier.
Consequences
The system goes to Motors Off state to protect the hardware.
Probable causes
This problem is most likely to occur when the incoming mains
voltage is too high to the rectifier.
Recommended actions
Check that the incoming mains voltage is according to
specification for the drive unit. Check that the correct voltage
is selected with jumpers on the transformer (optional).
