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, decimal):
Only for internal Siemens troubleshooting.
Remedy:
- carry-out a POWER ON (power off/on) for all components.
- upgrade the motor module software.
- upgrade the control unit software.
F01952
CU DRIVE-CLiQ: Synchronization of components not supported
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, 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
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, decimal):
Only for internal Siemens troubleshooting.
Remedy:
Carry-out a POWER ON (power off/on) for all components.
F01954
CU DRIVE-CLiQ: Synchronization not successful
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, 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).
A02000
Function generator: Start not possible
Reaction:
NONE
Acknowledge:
NONE
Cause:
The function generator has already been started.
Remedy:
Stop the function generator and restart again if necessary.

Function generator: Drive does not exist
Reaction:
NONE
Acknowledge:
NONE
Cause:
The drive object specified for connection does not exist.
