600
System fault
Communication between control board and power
unit has failed.
Reset the fault and restart.
Should the fault re-occur, contact your
distributor.
602
Watchdog has reset the CPU.
603
Voltage of auxiliary power in power unit is too low.
604
Phase fault: Voltage of an output phase does not
follow the reference.
605
CPLD has faulted but there is no detailed
information about the fault.
606
Control and power unit software are incompatible. Update software. Should the fault re-occur,
contact your distributor.
607
Software version cannot be read. There is no
software in the power unit.
Update power unit software. Should the fault
re-occur, contact your distributor.
608
CPU overload. Part of the software (for example,
the application) has caused an overload situation.
The source of the fault has been suspended.
Reset the fault and restart.
Should the fault re-occur, contact your
distributor.
609
Memory access has failed. For example, retain
variables could not be restored.
610
Necessary device properties cannot be read.
647
Software error.
Update the software. Should the fault re-
occur, contact your distributor.
648
Invalid function block used in application. System
software and application are not compatible.
649
Resource overload.
Error when loading parameter initial
values.
Error when restoring parameters.
Error when saving parameters.
9
80
Undervoltage (fault) DC-link voltage is under the voltage limits defined.
●
Most probable cause: too low a supply
voltage
●
AC drive internal fault
●
Defect input fuse
●
External charge switch not closed
NOTE: This fault is activated only if the drive is in
Run state.
In case of temporary supply voltage break
reset the fault and restart the AC drive.
Check the supply voltage. If it is adequate, an
internal failure has occurred. Contact your
distributor.
81
Undervoltage (alarm)
10
91
Input phase
Input line phase is missing.
Check supply voltage, fuses and cable.
11
100
Output phase
supervision
Current measurement has detected that there is
no current in one motor phase.
Check motor cable and motor.
13
120
AC drive
undertemperature
(fault)
Too low temperature measured in power unit’s
heatsink or board.
Heatsink temperature is under -10°C (14°F).
121
AC drive
undertemperature
(alarm)
