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 distrib-
utor.
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 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 val-
ues.
Error when restoring parameters.
Error when saving parameters.

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.

120
AC drive under-
temperature
(fault)
Too low temperature measured in power
unit’s heatsink or board. Heatsink tem-
perature is under -10 °C (14 °F).
