Possible cause
Communication between control
circuit and power unit has failed.
Communication interference
between control circuit and power
unit, but it is still working.
Watchdog has reset the CPU.
Auxiliary power voltage in power
unit is too low.
Phase fault: Voltage of an output
phase does not follow the reference.
CPLD has faulted, but there is no
detailed information about the fault.
Control panel and power unit
software are incompatible.
Software version cannot be read.
There is no software in the power
unit.
CPU overload. A part of the
software (for example application)
has caused an overload situation.
The source of fault has been
suspended.
Memory access has failed. For
example, retain variables could not
be restored.
Necessary device properties cannot
be read.
Configuration error.
Software error.
Invalid function block used in
application. System software and
application are not compatible.
Resource overload.
Error when loading parameter initial
values.
Error when restoring parameters.
Error when saving parameters.
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 occurs only if the
drive is in Run state.
Input line phase is missing.
Current measurement has detected
that there is no current in one of the
motor phases.
Remedy
Reset the fault and restart.
Contact the nearest distributor if
the fault reoccurs.
Update software. Contact the
nearest distributor if the fault
reoccurs.
Update power unit software.
Contact the nearest distributor if
the fault reoccurs.
Reset the fault and restart.
Contact the nearest distributor if
the fault reoccurs.
Update software. Contact the
nearest distributor if the fault
reoccurs.
In case of temporary supply
voltage failure, reset the fault
and restart the AC drive. Check
the supply voltage. If it is
adequate, an internal fault has
occurred.
Contact the nearest distributor.
Check supply voltage, fuses
and cable.
Check power cable and motor.
