ABSTRACT:
An ON-OFF control of a clutch-brake for a press machine, having fail-safe operation. The clutch-brake drive control is provided by turning double solenoid valves on and off. Two lines of drive control signal generators output drive control signals to semiconductor elements when a running command pulse signal is recognized as valid. A bus collating circuit forcibly cuts off AC power supplies of solenoid driving circuits when synchronization and coordination of the operation of each of the lines are checked and found not in coordination. Two lines of fault detecting circuitry forcibly cuts off the AC power supplies of the solenoid driving circuits by automatically detecting a fault of the semiconductor elements.
