What it means
F40825 means that a DRIVE-CLiQ component has lost its supply voltage: the DRIVE-CLiQ communication from the component involved to the Control Unit signals the failure. For this code the affected component is the DRIVE-CLiQ Hub Module (Hub) in the CX32 DRIVE-CLiQ group. The component reports the fault cause 9 (= 09 hex): the power supply voltage for the components has failed.
Why it appears
- The DRIVE-CLiQ communication from the involved DRIVE-CLiQ component to the Control Unit signals that the supply voltage has failed.
- The fault cause reported in the message value is 9 (= 09 hex): the power supply voltage for the components has failed.
What to check
- Carry out a POWER ON: switch the drive off and switch it on again.
- Check the supply voltage wiring of the DRIVE-CLiQ component — interrupted cable, contacts, and the like.
- Check the dimensioning of the DRIVE-CLiQ component power supply.
Reading the message value
- The drive codes the message value as 0000yyxx hex; it can be read in r0949 (fault value) or r2124 (alarm value).
- yy = component number of the DRIVE-CLiQ component that reported the failure.
- xx = error cause; for this fault the drive reports 9 (= 09 hex), the failed power supply voltage for the components.
Parameters the manual names
- r0949 (fault value) — shows the coded message value of this fault, from which the component number (yy) and the fault cause (xx) are read.
- r2124 (alarm value) — holds the same coded value in parallel, so the message value can also be read there.
Acknowledging and restarting
The fault must be acknowledged immediately. As the remedy prescribes, carry out a POWER ON: switch the drive off and switch it back on. Once the supply voltage wiring and the power supply dimensioning have been checked and the drive is switched on again, it can be restarted.
The same on every family
Every manual that describes F40825 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does SINAMICS fault F40825 mean?
A DRIVE-CLiQ component — for this code the DRIVE-CLiQ Hub Module (Hub) — has signalled to the Control Unit over DRIVE-CLiQ that its supply voltage has failed. The reported fault cause is 9 (= 09 hex): the power supply voltage for the components has failed.
How do I clear fault F40825?
Carry out a POWER ON (switch the drive off and on again), check the supply voltage wiring of the DRIVE-CLiQ component for an interrupted cable or poor contacts, and check the dimensioning of its power supply. Acknowledge the fault immediately.
How can I see which component triggered F40825?
Read the message value in r0949 or r2124. It is coded 0000yyxx hex, where yy is the component number and xx the error cause (9 = 09 hex for this fault).
Does F40825 appear on the S120 as well as the G130?
Yes — the fault is described with the same wording for the G130/G150 and for the S120/S150, in each case at the DRIVE-CLiQ Hub Module (Hub).
