Siemens SINAMICS G120XA - Rotation Monitoring; Function Plan and Time Response of the Speed Monitoring

6.7.6.6 Rotation monitoring
Function description
The converter monitors the speed or velocity of a machine component via an electromechanic
or electronic encoder, e.g. a proximity switch. Examples of how the function can be used:
● Drive belt monitoring for fans
● Blocking protection for pumps
The converter checks whether the encoder consistently supplies a 24 V signal during motor
operation. If the encoder signal fails for time p2192, the converter signals fault F07936.
