F01951 CU DRIVE-CLiQ: Synchronization application clock cycle missing
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 not successful.
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.
F01952 CU DRIVE-CLiQ: Synchronization of component not supported
Drive object: All objects
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The existing system configuration requires at 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 faulted 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.
A01953 CU DRIVE-CLiQ: Synchronization not completed
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.
Remedy: Carry out a POWER ON (power off/on) for all components.
F01954 CU DRIVE-CLiQ: Synchronization unsuccessful
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
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 and was not able to be successfully completed.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: 1. Ensure perfect functioning of the DRIVE-CLiQ.
2. Initiate a new synchronization, e.g. by:
- remove the PROFIBUS master and re-insert again.
- restart the PROFIBUS master.
- power-down the Control Unit and power-up again.
- press the Control Unit reset button.
- reset the parameter and download the saved parameters (p0009 = 30, p0976 = 2).
