SINAMICS DCM
886 List Manual (LH8), 02/2015, 6RX1800-0ED76
A01069 Parameter backup and device incompatible
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S, TM150, TM15DI_DO, TM31
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.
- save the parameters (p0977 = 1).
F01072 Memory card restored from the backup copy
Message value: -
Message class: General drive fault (19)
Drive object: All objects
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 value: -
Message class: General drive fault (19)
Drive object: All objects
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).
Reaction upon N: NONE
Acknowl. upon N: NONE
A01099 Tolerance window of time synchronization exited
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The time master exited the selected tolerance window for time synchronization.
See also: p3109 (RTC real time synchronization tolerance window)
Remedy: Select the re-synchronization interval so that the synchronization deviation between the time master and drive
system lies within the tolerance window.
