What it means
F35835 is raised for a Terminal Module (TM): a DRIVE-CLiQ communication error has occurred from the Control Unit to the Terminal Module involved, and the nodes no longer send and receive in synchronism. The manuals describe the code identically for the G130, G150, S120 and S150. The message value tells you which component dropped out of the cyclic exchange and why: the drive codes it in r0949 or r2124 as 0000yyxx hex, where yy is the component number and xx is the error cause.
Why it appears
- A DRIVE-CLiQ communication error has occurred from the Control Unit to the Terminal Module involved.
- The nodes do not send and receive in synchronism, so the cyclic exchange with the Terminal Module breaks down; which fault cause applied is recorded in the message value (decoded below).
What to check
- Read the message value in r0949 (or r2124): 0000yyxx hex names the Terminal Module involved (yy) and the fault cause (xx), so you know which component has failed.
- Carry out a POWER ON.
- If the fault occurs again, replace the component involved.
Reading the message value
- The manual prints the message value as
Component number: %1, fault cause: %2
. - The information is coded in the message value (r0949/r2124) as 0000yyxx hex: yy = component number, xx = error cause.
- Fault cause 33 (= 21 hex): the cyclic telegram has not been received.
- Fault cause 34 (= 22 hex): timeout in the telegram receive list.
- Fault cause 64 (= 40 hex): timeout in the telegram send list.
Parameters the manual names
- r0949 (fault value) — read the coded message value of this fault here: 0000yyxx hex, with the component number in yy and the error cause in xx.
- r2124 (alarm value) — named by the manual alongside r0949 as a place where the same coded message value can be read.
- p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave / DQ fault slave) — the remedy for this code cross-references this parameter; the manual adds no handling step for it here.
Acknowledging and restarting
Acknowledge the fault immediately; the drive is switched off (OFF1, alternatively OFF2) and does not restart until the fault has been acknowledged. The manual's remedy is to carry out a POWER ON. If F35835 occurs again, replace the component involved.
The same on every family
Every manual that describes F35835 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF1 (OFF2) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Terminal Module (TM) | SINAMICS S120, S150 List Manual · p. 3235 |
| G130, G150 | OFF1 (OFF2) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Terminal Module (TM) | SINAMICS G130, G150 List Manual · p. 1897 |

Questions technicians ask
What does fault F35835 mean on a SINAMICS drive?
A DRIVE-CLiQ communication error between the Control Unit and a Terminal Module: the nodes no longer send and receive in synchronism, so the cyclic telegram is missing or a receive/send list runs into a timeout.
How do I decode the F35835 message value?
Read r0949 (or r2124): the value 0000yyxx hex gives yy as the component number and xx as the fault cause — 33 (= 21 hex) cyclic telegram not received, 34 (= 22 hex) receive-list timeout, 64 (= 40 hex) send-list timeout.
How do I clear F35835?
Acknowledge the fault immediately and carry out a POWER ON. If the fault occurs again, the manual says to replace the component involved.
Which component does F35835 point to?
The Terminal Module (TM) involved; its number is coded as yy in the message value and the fault cause as xx.
