Warnings, faults and system messages
9.6 List of fault codes and alarm codes
Remedy:
If required, deactivate and clear the buffer memory (p0014 = 0).
If required, clear the buffer memory (p0014 = 2).
In the following cases, the entries in the buffer memory are transferred into the ROM and then the buffer memory is cleared:
- p0971 = 1
- switch-off/switch-on Control Unit
See also: p0014 (Buffer memory mode)
F01068
CU: Data memory memory overflow
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
Reaction:
NONE
Acknowledge:
NONE
Cause:
The parameter backup on the memory card and the drive unit 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.
- save the parameters (p0971 = 1).
F01072
Memory card restored from the backup copy
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
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).
Remedy:
- carry out a POWER ON (power off/on) for the Control Unit.
- carry out a hardware reset (RESET button, p0972).
