Description
This function allows the mechanical force transmission between the motor and motor load to
be monitored. Typical applications include, for example, pulley belts, flat belts or chains, or
pulleys for toothed wheels of motor-in and motor-out shafts which then transmit
circumferential velocities and circumferential forces (see figure below). The load torque
monitoring function can then detect whether the motor load is locked or the force
transmission has been interrupted.
