Denso RC5 manual Wiring of Primary Power Source, Robot Controller Power Supply Specifications

7.2Wiring of Primary Power Source

Observe the following precautions when wiring the primary power source of the robot controller:

(1)Connect the robot power cable to a power source separate from the welder power source.

(2)Ground the grounding wire (green) of the robot power cable.

(3)Ground the grounding terminal of the robot controller using a wire of 1.25 mm2 or more in size.

(4)For the robot power supply, use a grounding wire with grounding resistance of 100 Ω or less.

(5)If the supply power source for the robot controller requires a leakage breaker, use a high frequency-proof leakage breaker for inverters.

(6)Prepare wires of an appropriate capacity for the 200 VAC main line and other cables according to the tables given below.

Caution: If ERROR6102 (power voltage drop) occurs when the robot is in operation, then it may be due to an insufficient capacity of the primary power source.

(7)Do not bundle the teach pendant cables, I/O cables or motor cables together with high power lines such as 200 VAC lines and peripheral device cables, or route the motor cables near high power devices (motor, welder, parts feeder, etc.).

(8)Do not route any additional cables or air tubes of end-effectors through the robot unit. Doing so will result in broken cables or tubes.
