What it means
F01952 means that the DRIVE-CLiQ components connected to the CU do not all support the synchronization between the basic clock cycle, the DRIVE-CLiQ clock cycle and the application clock cycle, although the existing system configuration requires exactly this. The drive switches off and the fault must be acknowledged before it can be restarted.
Why it appears
- The existing system configuration requires that the connected DRIVE-CLiQ components support the synchronization between the basic clock cycle, the DRIVE-CLiQ clock cycle and the application clock cycle.
- However, not all DRIVE-CLiQ components have this functionality — the fault is raised when a component in the configuration lacks it.
What to check
- Read the fault value in r0949 to find the component number of the first faulty DRIVE-CLiQ component (interpret the value decimal).
- Upgrade the firmware of the component specified in the fault value.
- If required, also upgrade additional components in the DRIVE-CLiQ line.
Reading the message value
- The message value holds the component number of the first faulty DRIVE-CLiQ component; it is stored in r0949 and must be interpreted as a decimal number.
Parameters the manual names
- r0949 — fault value: read the component number of the first faulty DRIVE-CLiQ component here and interpret it decimal to identify the component whose firmware must be upgraded.
Acknowledging and restarting
Once the firmware of the component named in the fault value has been upgraded, acknowledge the fault immediately. If required, also perform a POWER ON — switch the drive off and back on — before restarting.
The same on every family
Every manual that describes F01952 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 (NONE) | IMMEDIATELY (POWER ON) | Internal (DRIVE-CLiQ) communication error (12) | None | SINAMICS S120, S150 List Manual · p. 2720 |
| G130, G150 | OFF2 (NONE) | IMMEDIATELY (POWER ON) | Internal (DRIVE-CLiQ) communication error (12) | None | SINAMICS G130, G150 List Manual · p. 1496 |

Questions technicians ask
What does SINAMICS fault F01952 mean?
It means that not all connected DRIVE-CLiQ components support the synchronization between the basic clock cycle, the DRIVE-CLiQ clock cycle and the application clock cycle that the existing system configuration requires.
How do I find the faulty component with F01952?
The fault value in r0949 contains the component number of the first faulty DRIVE-CLiQ component; interpret the value as a decimal number.
How is fault F01952 cleared?
Upgrade the firmware of the component specified in the fault value and, if required, also upgrade additional components in the DRIVE-CLiQ line. Then acknowledge the fault immediately; if required, perform a POWER ON before restarting.
