What it means
A49170 is raised when the cooling unit signals a general alarm to the drive. The code is described for SINAMICS G130, G150, S120 and S150, with the same meaning and the same checks on each of them. No message value is supplied with this alarm, so there is no value to decode.
Why it appears
- The cooling unit reports a general alarm to the drive.
What to check
- Inspect the wiring between the cooling unit and the input terminal (Terminal Module).
- Inspect the external control device for the cooling unit.
Acknowledging and restarting
This alarm needs no acknowledgment: the drive keeps running while it is active, and A49170 clears by itself once the cooling unit stops signalling.
