Wiring of Primary Power Source
Observe the following precautions when wiring the primary power source of the robot controller:
About Primary Power Source
- Use the correct power source (200 VAC or 100 VAC) for the controller specification.
- Be careful not to confuse AC 100V with AC 200V (or AC 230V), and also three-phase with single-phase.
- Connect the robot power cable to a power source separate from the welder power source.
- To cut off the controller power supply, use customer-prepared-breaker.
Protective Grounding
Before connecting the power cable, make sure to connect 2.5mm＾2 or higher level of wire (yellow/green) to the earth terminal (protective grounding) of the front metal panel. When disconnecting the bonding wire connected to the earth terminal (protective grounding) of the front metal panel, make sure to disconnect the power cable beforehand.
Additional Precautions
- Do not bundle the teach pendant cable, I/O cables or motor & encoder cable together with high power lines such as power cables and peripheral device cables, or route the motor cables near high power devices (motor, welder, parts feeder, etc.).
- 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.
- When you connect the controller's functional grounding, ground a wire with 1.25mm2 or larger.
