Abstract
Two emergency stop lines are provided. Due to contacts being opened by commands from emergency stop factors and from first and second CPUs, conducting to first and second contactors are stopped. Contacts of the contactors are opened, and power supply to the motor is interrupted, whereby an emergency stop is performed. Further, the first CPU on the first line transmits an abnormality signal to the second CPU when the states of the contacts on the self emergency stop line, detected by digital inputs, are abnormal, and the second CPU opens a contact on the self emergency stop line so as to cause the contactor to be non-excited to thereby stop power supply to the motor.
