What it means
F36851 reports a DRIVE-CLiQ communication error from the DRIVE-CLiQ Hub Module in question to the Control Unit (CU): the DRIVE-CLiQ component did not set the sign-of-life to the Control Unit. The fault cause is 10 (= 0A hex), meaning that the sign-of-life bit in the receive telegram is not set.
Why it appears
- A DRIVE-CLiQ communication error between the DRIVE-CLiQ Hub Module in question and the Control Unit.
- The DRIVE-CLiQ component did not set the sign-of-life to the Control Unit.
- Fault cause 10 (= 0A hex): the sign-of-life bit in the receive telegram is not set.
What to check
- Upgrade the firmware of the component involved — this is the remedy the manuals give for this fault.
Reading the message value
- The message value contains the component number and the fault cause, printed in the manual as
Component number: %1, fault cause: %2
. - The individual information is coded in the message value (r0949/r2124) as 0000yyxx hex: yy = component number, xx = error cause.
- Fault cause 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 message value of F36851 here — 0000yyxx hex yields the component number (yy) and the fault cause (xx).
- r2124 (alarm value): the same coded value for this message is readable here.
Acknowledging and restarting
Acknowledge this fault immediately once the firmware of the component involved has been upgraded.

Questions technicians ask
What does fault F36851 mean on a SINAMICS drive?
It is a DRIVE-CLiQ communication error from the DRIVE-CLiQ Hub Module in question to the Control Unit: the component did not set the sign-of-life to the CU. Fault cause 10 (= 0A hex) means the sign-of-life bit in the receive telegram is not set.
How can I see which component triggered F36851?
Read the message value in r0949 (or r2124). It is coded 0000yyxx hex, where yy is the component number and xx is the error cause.
How do I clear fault F36851?
The remedy given in the manuals is to upgrade the firmware of the component involved. Afterwards, the fault must be acknowledged immediately.
