摘要： PROBLEM TO BE SOLVED: To reduce the number of wiring lines and the types and number of cable lengths. SOLUTION: This robot control system is provided with a robot part 3 including a robot arm 32 and a servomotor 31 built in the robot part 3, a servo amplifier 2 driving the servomotor, and a control part 1 which commands the servo amplifier to control the robot arm. A sending/receiving means between the control part 1 and the robot part 3 is integrated into a sending/receiving means between the controlling part 1 and the servo amplifier 2 and a sending/receiving means between the servo amplifier 2 and the robot part 3 so that sending and receiving between the controlling part 1 and the robot part 3 may be performed through the servo amplifier 2. A command from the controlling part 1 to the robot part 3 and a feedback signal and detecting signal from the controlling part 3 to the controlling part 1 are performed through the servo amplifier 2. It is thus possible to eliminate cables connected between the controlling part 1 and the robot part 3, thereby reducing the types and number of lengths of the cables arranged so as to meet setting conditions between the controlling part 1, the servo amplifier 2, and the robot part 3.
