Description
The forced checking procedure (test stop) of the basic functions is an inverter self test. The
inverter checks its circuits to switch off the torque. If you are using the Safe Brake Relay, for
a forced checking procedure, the inverter also checks the circuits of this component.
You start the forced checking procedure each time that the STO function is selected.
Using a timer block, the inverter monitors as to whether the forced checking procedure is
regularly performed.
