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:
• Gearbox monitoring for traction drives and hoisting gear
• Drive belt monitoring for fans and conveyor belts
• Blocking protection for pumps and conveyor belts
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.
