4.2 List of faults and alarms
SINAMICS DCP
398 List Manual (LH21), 05/2016
A01073 (N) POWER ON required for backup copy on memory card
Drive object: All objects
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).
A01099 Tolerance window of time synchronization exited
Drive object: All objects
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.
See also: r3108 (RTC last synchronization deviation)
A01100 CU: Memory card withdrawn
Drive object: DCP_CTRL
Cause: The memory card (non-volatile memory) was withdrawn during operation.
Notice:
It is not permissible for the memory card to be withdrawn or inserted under voltage.
Remedy: - power down the drive system.
- re-insert the memory card that was withdrawn - this card must match the drive system.
- power up the drive system again.
A01104 CU: Do not power down. File system being optimized.
Drive object: All objects
Cause: The file system is currently being optimized in the non-volatile device memory of the Control Unit. This process may
take several minutes.
Notice:
The Control Unit must not be powered down during optimization, as this can lead to user data being lost.
Remedy: Leave the Control Unit powered up during optimization.
Note:
The alarm disappears automatically once file system optimization is complete.
F01105 (A) CU: Insufficient memory
Drive object: All objects
Cause: Too many functions have been configured on this Control Unit (e.g. too many drives, function modules, data sets, OA
applications, blocks, etc).
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - change the configuration on this Control Unit (e.g. fewer drives, function modules, data sets, OA applications,
blocks, etc).
- use an additional Control Unit.
F01106 CU: Insufficient memory
Drive object: DCP_CTRL, TM150
Cause: There is not sufficient free memory space available.
Remedy: Not necessary.
