What it means
F36875 (HUB: power supply voltage failed) is raised when the DRIVE-CLiQ communication from the DRIVE-CLiQ component involved to the Control Unit signals that the supply voltage has failed. The fault cause reported with the message is 9 (= 09 hex): the power supply voltage for the components has failed.
Why it appears
- The DRIVE-CLiQ component involved reports to the Control Unit, via DRIVE-CLiQ communication, that its supply voltage has failed — fault cause 9 (= 09 hex).
What to check
- Carry out a POWER ON (switch-off/switch-on).
- Check the power supply voltage wiring for the DRIVE-CLiQ component — interrupted cable, contacts.
- Check the dimensioning of the power supply for the DRIVE-CLiQ component.
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.
- Both items are coded in the message value (r0949/r2124) as 0000yyxx hex, where yy is the component number and xx the error cause.
- For this fault the error cause is 9 (= 09 hex), the failed power supply voltage.
Parameters the manual names
- r0949 (fault value) — read the coded message value 0000yyxx hex here to identify the component number (yy) and the fault cause (xx) behind F36875.
- r2124 (alarm value) — carries the same coded value and can be read alongside r0949.
Acknowledging and restarting
Acknowledge the fault and carry out a POWER ON (switch off/on) as the remedy prescribes. If F36875 reappears after the power on, work through the wiring and power supply dimensioning checks above before returning the drive to service.
The same on every family
Every manual that describes F36875 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does fault F36875 mean on a SINAMICS drive?
The DRIVE-CLiQ component involved has signalled to the Control Unit that its power supply voltage has failed; the reported fault cause is 9 (= 09 hex).
How do I clear F36875?
Acknowledge the fault and carry out a POWER ON (switch off/on). Then check the power supply voltage wiring of the DRIVE-CLiQ component and the dimensioning of its power supply.
Where can I read out the details behind F36875?
In the message value in r0949 or r2124, coded as 0000yyxx hex: yy gives the component number and xx the error cause, which is 9 for this fault.
