What it means
F32850 reports that an internal software error has occurred in the Sensor Module that evaluates encoder 2. The drive stores a numerical fault value in r0949, to be interpreted as a decimal number, which identifies exactly which internal error was detected. Depending on how the drive is configured, the same condition can also be issued as an alarm (A) or as a message without any reaction (N) instead of a fault.
Why it appears
- An internal software error occurred in the Sensor Module of encoder 2; the fault value in r0949 identifies the specific error.
- According to the fault value, the underlying problems range from a blocked background time slice, an incorrect checksum over the code memory or data that cannot be interpreted in the OEM memory of the EnDat encoder, to incorrect EEPROM descriptive, calibration or configuration data, faulted communication with the analog/digital converter, or a DRIVE-CLiQ encoder initialization error.
What to check
- Read the fault value in r0949 as a decimal number to identify which internal error the Sensor Module detected.
- Replace the Sensor Module.
- If required, upgrade the firmware in the Sensor Module.
- Contact Technical Support.
Reading the message value
The fault value is stored in r0949 and must be interpreted as a decimal number:
- 1: Background time slice is blocked.
- 2: Checksum over the code memory is not OK.
- 10000: OEM memory of the EnDat encoder contains data that cannot be interpreted.
- 11000 ... 11499: Descriptive data from EEPROM incorrect.
- 11500 ... 11899: Calibration data from EEPROM incorrect.
- 11900 ... 11999: Configuration data from EEPROM incorrect.
- 12000 ... 12008: communication with analog/digital converter faulted.
- 16000: DRIVE-CLiQ encoder initialization application error.
- 16001: DRIVE-CLiQ encoder initialization ALU error.
- 16002: DRIVE-CLiQ encoder HISI / SISI initialization error.
- 16003: DRIVE-CLiQ encoder safety initialization error.
- 16004: DRIVE-CLiQ encoder internal system error.
Parameters the manual names
- r0949 — fault value of this message; read it as a decimal number to determine which internal software error the Sensor Module of encoder 2 reported.
Acknowledging and restarting
F32850 can only be acknowledged by switching the power supply off and on again (POWER ON); the drive accepts no restart until this has been done. If the fault comes back after the power cycle, work through the remedy steps above — replace the Sensor Module, upgrade its firmware if required, and otherwise contact Technical Support.
What differs between the drive families
Straight from the manuals' own fields — F32850 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) | POWER ON | Hardware/software error (1) | Sensor Module Encoder 2 | SINAMICS S120, S150 List Manual · p. 3121 |
| G130, G150 | OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) | POWER ON | Hardware/software error (1) | Sensor Module Encoder 2 | SINAMICS G130, G150 List Manual · p. 1798 |
The drives this code lives on
F32850 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 SINAMICS fault F32850 mean?
It means an internal software error has occurred in the Sensor Module that evaluates encoder 2. The decimal fault value in r0949 identifies which internal error was detected.
How do I clear fault F32850?
Only by switching the power supply off and on again (POWER ON). If the fault recurs, replace the Sensor Module, upgrade its firmware if required, or contact Technical Support.
What does a fault value of 16000 to 16004 for F32850 mean?
These values are DRIVE-CLiQ encoder initialization errors — for example 16004 is an internal system error of the DRIVE-CLiQ encoder.
Can F32850 also appear as an alarm?
Yes. Depending on the drive's configuration, the same condition can also be issued as an alarm (A) or as a message without any reaction (N) instead of a fault.
