Possible cause
Communication between control cir-
cuit 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 de-
tailed information about the fault.
Control panel and power unit soft-
ware 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) causes an
overload situation. The source of the
fault is suspended.
Memory access has failed. For ex-
ample, retain variables could not be
restored.
Necessary device properties cannot
be read.
Configuration error.
Software error.
Invalid function block is used in the
application. System software and ap-
plication are not compatible.
Resource overload.
Error when loading parameter initial
values.
Error when restoring parameters.
Error when saving parameters.
fined.
• the most probable cause: supply
voltage is too low
• AC drive internal fault
• defective input fuse
• external charge switch is not
closed
Note! This fault occurs only if the
drive is in Run state.
Remedy
Reset the fault and restart.
Contact the nearest distributor if
the fault reoccurs.
Update software. Contact the
nearest distributor if the fault re-
occurs.
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 re-
occurs.
In case of temporary supply volt-
age failure, reset the fault and re-
start the AC drive. Check the
supply voltage. If it is adequate,
an internal fault has occurred.
Contact the nearest distributor.
