Fault Codes and Descriptions, continued
Fault
Code Fault
ID
Fault Name Possible Cause Remedy
7 60 Saturation Various causes:
•
Defective component
• Brake resistor short-circuit or overload
• Cannot be reset from keypad
• Switch off power
• DO NOT RECONNECT POWER! Contact
factory
• If this fault appears simultaneously with
F1, check motor cables and motor
8 600 System fault Communication between control board
and power unit has failed Reset the fault and restart. Should the fault
re-occur, contact the distributor near you
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 the distributor near you
607 Software version cannot be read. There is
no software in power unit Update power unit software. Should the fault
re-occur, contact the distributor near you
608 CPU overload. Some part of the software
(for example application) has caused an
overload situation. The source of fault
has been suspended Reset the fault and restart. Should the fault
re-occur, contact the distributor near you
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 the distributor near you
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 the distributor
near you
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
