By increasing the standstill time t, a possible alternate switching on and off of the output relays can then be avoided. By increasing the time period until the output relays are released, it can also be achieved that, depending on the run-down behavior of the motor, the safety relays are not switched until the motor has come to an absolute standstill, especially in the case of motors that generate a...
