What it means
F32805 is raised when the drive finds corrupted data in the EEPROM of Sensor Module Encoder 2. The S120/S150 manual words this as corrupted EEPROM data, the G130/G150 manual as corrupted internal parameter data — in both cases the data stored in the module is no longer intact. Depending on how the drive is configured, the same condition can also be issued as an alarm or with no reaction instead of a fault.
Why it appears
- The data stored in the EEPROM of Sensor Module Encoder 2 is corrupted — the module's internal parameter data is no longer intact.
What to check
- Read the fault value in r0949 and interpret it in hexadecimal to see which of the two errors the drive has detected (see the list below).
- Replace Sensor Module Encoder 2 — this is the manual's remedy for both fault values, on G130/G150 as well as on S120/S150.
- Acknowledge the message immediately after the replacement; the drive will only restart once the fault has been cleared.
Reading the message value
The drive stores the fault value in r0949; interpret it in hexadecimal:
- 01: EEPROM access error.
- 02: Too many blocks in the EEPROM.
Parameters the manual names
- r0949 — holds the fault value of this message; read it in hexadecimal to tell an EEPROM access error (01) apart from too many blocks in the EEPROM (02).
Acknowledging and restarting
The fault is acknowledged immediately, after which the drive can be started again. Because the remedy is replacement of Sensor Module Encoder 2, acknowledge once the module has been exchanged. If the condition is configured as an alarm or with no reaction instead, the drive takes no action and there is nothing to acknowledge (reaction and acknowledgement NONE).
What differs between the drive families
Straight from the manuals' own fields — F32805 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Servo: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) Vector: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) Hla: OFF1 (NONE, OFF2, OFF3) | IMMEDIATELY | Hardware/software error (1) | Sensor Module Encoder 2 | SINAMICS S120, S150 List Manual · p. 3116 |
| G130, G150 | OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) | IMMEDIATELY | Hardware/software error (1) | Sensor Module Encoder 2 | SINAMICS G130, G150 List Manual · p. 1793 |
The drives this code lives on
F32805 is described for G130, G150, S120, S150. These are the converters of those families in our catalogue — price on request.
Questions technicians ask
What does fault F32805 mean on a SINAMICS drive?
The EEPROM data of Sensor Module Encoder 2 is corrupted, so the module's internally stored parameter data can no longer be considered intact. The manual's remedy is to replace the module.
How do I clear fault F32805?
Replace Sensor Module Encoder 2 and then acknowledge the fault immediately. Before replacing, you can read r0949 in hexadecimal to see whether it was an EEPROM access error (01) or too many blocks in the EEPROM (02).
Can F32805 appear as an alarm instead of a fault?
Yes. Depending on the drive configuration, the same condition can also be issued as an alarm (A) or with no reaction (N), in which case no acknowledgement is required.
