A01064 (F) CU: Internal error (CRC)
Message class: Hardware/software error (1)
Reaction: NONE
Acknowledge: NONE
Cause: A checksum error (CRC error) has occurred in the Control Unit program memory
Remedy: - carry out a POWER ON (switch-off/switch-on) for all components.
- upgrade firmware to later version.
- contact Technical Support.
F01068 CU: Data memory memory overflow
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The utilization for a data memory area is too large.
Fault value (r0949, interpret binary):
Bit 0 = 1: High-speed data memory 1 overloaded
Bit 1 = 1: High-speed data memory 2 overloaded
Bit 2 = 1: High-speed data memory 3 overloaded
Bit 3 = 1: High-speed data memory 4 overloaded
Remedy: - deactivate the function module.
- deactivate drive object.
- remove the drive object from the target topology.
A01069 Parameter backup and device incompatible
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The parameter backup (on the memory card or in the drive unit) and the drive device do not match. The module boots
with the factory settings.
Example:
Devices A and B. are not compatible and a memory card with the parameter backup for device A is inserted in device
B.
Remedy: - insert a memory card with compatible parameter backup and carry out a POWER ON.
- insert a memory card without parameter backup and carry out a POWER ON.
- if required, withdraw the memory card and carry out POWER ON.
- carry out a hardware reset (p0972 = 1).
- save the parameters (p0971 = 1).
F01072 Memory card restored from the backup copy
Message class: General drive fault (19)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The Control Unit was switched-off while writing to the memory card. This is why the visible partition became
defective.
After switching on, the data from the non-visible partition (backup copy) were written to the visible partition.
Remedy: Check that the firmware and parameterization is up-to-date.
A01073 (N) POWER ON required for backup copy on memory card
Message class: General drive fault (19)
Reaction: NONE
Acknowledge: NONE
Cause: The parameter assignment on the visible partition of the memory card has changed.
In order that the backup copy on the memory card is updated on the non-visible partition, it is necessary to carry out
a POWER ON or hardware reset (p0972) of the Control Unit.
Note:
It is possible that a new POWER ON is requested via this alarm (e.g. after saving with p0971 = 1).
