Abstract

PURPOSE: To perform interlocking when a wrong transmission is detected, by supervising whether or not the output pulse train of pulse generator is accurately transmitting the position information to an electric circuit of numerical controller.
CONSTITUTION: When noises go on the output signal lines A-CH, B-CH, Z-CH of the pulse generator and a reversible counter 7 performs incorrect counting and a trouble occurs in a position detecting circuit, the output of an exclusive OR circuit 11 becomes "1" and an incorrect counting detection circuit 12 receives the output of the circuit 11, a SETUP signal and the A-CH signal to generate an output MIS. The output MIS becomes "1" only when the SETUP signal is "0", the A-CH signal is "1" and the output of the circuit 11 is "1". The output MIS is always coupled to an emergency stop flip-flop 13. When the output MIS becomes "1", the flip-flop 13 is set and its output signal EMS becomes "1" to disconnect a servomotor from a servoamplifier. Then, the motor is braked and interlocking is performed
