Overview of Alarms
SINAMICS-Alarms
201950 <location>IF1: PB/PN clock cycle synchronous operation
synchronization unsuccessful
Message -
value:
Drive object: All objects
Reaction: OFF1 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Synchronization of the internal clock cycle to the global control telegram has failed. The internal clock
cycle exhibits an unexpected shift.
Remedy: Only for internal Siemens troubleshooting.
Note:
IF1: Interface 1
PB: PROFIBUS
PN: PROFINET
201951 <location>CU DRIVE-CLiQ: Synchronization application clock cycle
missing
Message %1
value:
Drive object: All objects
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: If DRIVE-CLiQ components with different application clock cycle are operated at a DRIVE-CLiQ port,
then this requires synchronization with the Control Unit.
This synchronization routine was unsuccessful.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (power off/on) for all components.
- upgrade the software of the DRIVE-CLiQ components.
- upgrade the Control Unit software.
201952 <location>CU DRIVE-CLiQ: Synchronization of component not
supported
Message %1
value:
Drive object: All objects
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The existing system configuration requires that the connected DRIVE-CLiQ components support the
synchronization between the basic clock cycle, DRIVE-CLiQ clock cycle and the application clock
cycle.
However, not all DRIVE-CLiQ components have this functionality.
Fault value (r0949, interpret decimal):
Component number of the first faulty DRIVE-CLiQ component.
Remedy: Upgrade the firmware of the component specified in the fault value.
Note:
If required, also upgrade additional components in the DRIVE-CLiQ line.
201953 <location>CU DRIVE-CLiQ: Synchronization not completed
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: After the drive system is powered up, the synchronization between the basic clock cycle, DRIVE-CLiQ
clock cycle and application clock cycle was started but was not completed within the selected time
tolerance.
Alarm value (r2124, interpret decimal):
Only for internal Siemens troubleshooting.
