What it means
F32405 is raised when the evaluation electronics of Encoder 2 (Sensor Module Encoder 2) report an inadmissibly high temperature. The evaluation belongs to a motor connected via DRIVE-CLiQ; on G130 and G150 the manual gives the fault threshold as 125 °C. Depending on how the drive is configured, the same condition can also be output as an alarm or with no reaction at all.
Why it appears
- An inadmissibly high temperature was detected in the encoder electronics or in the encoder evaluation of a motor with DRIVE-CLiQ.
What to check
- Read the measured temperature from the fault value r0949 to see how hot the evaluation actually got (decoding below).
- Lower the ambient temperature at the DRIVE-CLiQ connection of the motor.
Reading the message value
- On S120/S150, r0949 is interpreted hexadecimal: yyxxxx hex — yy = temperature sensor number, xxxx = measured module temperature in 0.1 °C. The message value itself carries the temperature (%1, in 0.1 °C) and the temperature sensor number (%2).
- On G130/G150, r0949 is interpreted decimal and holds the measured board/module temperature in 0.1 °C.
Parameters the manual names
- r0949 — fault value; for F32405 it carries the temperature measured in the encoder evaluation, decoded as described above.
Acknowledging and restarting
Acknowledge the fault immediately once the temperature has dropped; POWER ON is required. Where the same condition is configured as an alarm or without reaction, no acknowledgement is necessary.
What differs between the drive families
Straight from the manuals' own fields — F32405 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Servo: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, STOP2) Vector: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, STOP2) Hla: OFF1 (NONE, OFF2, OFF3, STOP2) | IMMEDIATELY (POWER ON) | Overtemperature of the electronic components (6) | Sensor Module Encoder 2 | SINAMICS S120, S150 List Manual · p. 3102 |
| G130, G150 | OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, STOP2) | IMMEDIATELY (POWER ON) | Overtemperature of the electronic components (6) | Sensor Module Encoder 2 | SINAMICS G130, G150 List Manual · p. 1780 |

Questions technicians ask
What does fault F32405 mean on a SINAMICS drive?
The evaluation electronics of Encoder 2 have detected an inadmissibly high temperature; on G130 and G150 the fault threshold is 125 °C.
How do I clear fault F32405?
Reduce the ambient temperature at the DRIVE-CLiQ connection of the motor, then acknowledge the fault immediately — POWER ON is required.
Which parameter shows the temperature of fault F32405?
r0949. On S120/S150 read it in hexadecimal (yy = temperature sensor number, xxxx = measured module temperature in 0.1 °C); on G130/G150 read it in decimal, in 0.1 °C.
Can F32405 also appear as an alarm?
Yes — depending on the drive configuration, the same condition can also be output as an alarm or without any reaction.
