14.11.16.5 Load monitoring failure detection
Overview
The "Load monitoring failure detection" function evaluates a periodic binary signal. A missing
signal indicates that the motor and the load are no longer mechanically coupled.
Description of function
The converter monitors the speed or velocity of a machine component using an
electromechanical or electronic sensor, e.g. a proximity switch.
The converter evaluates whether the sensor periodically delivers a 24 V signal during motor
operation. If the sensor signal is missing for time p2192, the converter signals fault F07936.
