Abstract

PURPOSE:To immediately stop the operation if a command pulse is not completely transmitted to a servocontrol section, by transmitting a command signal from an operation section to a servocontrol section with the monitoring at any time. CONSTITUTION:If an output of a flip-flop circuit 3 is not received at a servocontrol section 4, a reception signal from the section 4 is not returned to the circuit 3, and an output at a terminal Q of the circuit 3 keeps H level even at the next transmission of output pulse of an operation section 2. Thus, when the time of a timer circuit 71 of a discrimination circuit 7 is set a little shorter than a pulse interval, the output of an AND circuit 72 goes to H level at the end of this time set to set a flip-flop circuit 73 constituting a holding circuit 73 and an alarm of failure. The sections 2 and 4 receives this failure alarm signal and stop the operation.
