What it means
Fault F36805 (Hub: EEPROM checksum incorrect) is raised when the internal parameter data on the DRIVE-CLiQ Hub Module is incorrect. The alarm value stored in r2124 tells which of two EEPROM conditions the module found (see fault value). Depending on how the drive is configured, the same condition can also be output as an alarm (A) or as a message with no reaction (N) instead of a fault.
Why it appears
- The internal parameter data on the DRIVE-CLiQ Hub Module is incorrect.
What to check
- Check whether the permissible ambient temperature for the component is maintained.
- Replace the DRIVE-CLiQ Hub Module.
Reading the message value
The message value is the alarm value, which the drive also stores in r2124. Interpret it hexadecimal:
- 01 — EEPROM access error.
- 02 — Too many blocks in the EEPROM.
Parameters the manual names
- r2124 — alarm value of this message; read it hexadecimal to see whether the hub reported 01 (EEPROM access error) or 02 (too many blocks in the EEPROM).
Acknowledging and restarting
The fault is acknowledged by switching the power supply off and on again (POWER ON). The drive does not take any protective action on this fault, so once the drive has been powered up again the message is cleared. Where the drive is configured to output the condition only as an alarm or without any reaction, no acknowledgement is required.
The same on every family
Every manual that describes F36805 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | IMMEDIATELY (POWER ON) | Hardware/software error (1) | Terminal Board (TB) | SINAMICS S120, S150 List Manual · p. 3252 |
| G130, G150 | NONE | IMMEDIATELY (POWER ON) | Hardware/software error (1) | Terminal Board (TB) | SINAMICS G130, G150 List Manual · p. 1914 |

Questions technicians ask
What does fault F36805 mean on a SINAMICS drive?
It reports that the internal parameter data on the DRIVE-CLiQ Hub Module is incorrect. The alarm value in r2124 shows which of the two EEPROM conditions occurred.
How do I clear fault F36805?
Switch the power supply off and on again — the fault is acknowledged with POWER ON. If it comes back, check the ambient temperature and replace the DRIVE-CLiQ Hub Module.
What do alarm values 01 and 02 of F36805 in r2124 mean?
Read r2124 hexadecimal: 01 means an EEPROM access error, 02 means too many blocks in the EEPROM. Both point to the incorrect internal parameter data on the hub.
Can F36805 appear as an alarm instead of a fault?
Yes. Depending on how the drive is configured, the same condition can also be output as an alarm (A) or as a message with no reaction (N).
