Abstract
A robot control system including a servo amplifier supplying power to a robot, a processor controlling the operation of the robot, and a servo power connection/cutoff circuit connected to the same, issuing excitation/nonexcitation commands to a charging relay and a main circuit connection electromagnetic contactor provided in the circuit from the processor, monitoring the opened/closed states of the contacts of the charging relay and main circuit connection electromagnetic contactor by the processor, and detecting if their contacts open and close as instructed by the processor to thereby check if the power connection/cutoff circuit has a fault. Due to this, it is possible to provide a robot control system which detects faults of the power connection/cutoff circuit and which is inexpensive and high in safety.
