What it means
F35801 TM DRIVE-CLiQ: Sign-of-life missing reports a DRIVE-CLiQ communication error between the Control Unit and the Terminal Module involved: the sign-of-life bit in the receive telegram is not set (fault cause 10 (= 0A hex)). Depending on how the drive is configured, the same condition can also be issued as an alarm or without any reaction.
Why it appears
- A DRIVE-CLiQ communication error has occurred between the Control Unit and the Terminal Module involved.
- The sign-of-life bit in the receive telegram is not set (fault cause 10 (= 0A hex)).
What to check
- Read the component number from the message value to identify the Terminal Module involved (see the decoding below).
- Check the DRIVE-CLiQ connection to this Terminal Module.
- Replace the component involved.
Reading the message value
- The drive codes the message value in r0949 (fault value) or r2124 (alarm value) as 0000yyxx hex: yy = component number, xx = error cause.
- For this fault the error cause is 10 (= 0A hex): the sign-of-life bit in the receive telegram is not set.
Parameters the manual names
- r0949 (fault value): read the coded component number and fault cause here when the message appears as a fault.
- r2124 (alarm value): carries the same 0000yyxx hex coding when the message is issued as an alarm.
- p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave, DQ fault slave): the remedy for this fault cross-references this parameter.
Acknowledging and restarting
The drive takes no automatic reaction to this fault. Once the DRIVE-CLiQ connection has been repaired or the component involved replaced, the fault must be acknowledged immediately before the drive is restarted. When the drive is configured to issue the condition as an alarm or without reaction, neither a reaction nor an acknowledgement applies.
The same on every family
Every manual that describes F35801 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |

Questions technicians ask
What does fault F35801 mean on a SINAMICS drive?
It is a DRIVE-CLiQ communication error between the Control Unit and the Terminal Module involved: the sign-of-life bit in the receive telegram is not set, which the drive reports as fault cause 10 (= 0A hex).
How do I fix F35801?
Check the DRIVE-CLiQ connection to the Terminal Module identified by the component number in the message value, replace the component involved if necessary, then acknowledge the fault immediately.
Where can I see which Terminal Module triggered F35801?
The message value in r0949 (or r2124 when issued as an alarm) is coded 0000yyxx hex: yy gives the component number and xx gives the error cause.
Does F35801 shut the drive down?
No, the drive takes no automatic reaction, but the fault must be acknowledged immediately. Depending on the drive configuration it can also appear as an alarm or without any reaction, in which case no acknowledgement is required either.
