Noise countermeasures
The robot cables which are connected to the controller's XM and YM connectors are
motor power cables, and these cables emit switching noise which occurs during motor
control.
This noise could cause malfunctions in sensors, etc., which are located near these motor
cables. If such malfunctions occur, the following countermeasures are recommended.
1) Install the sensor, etc., further away from the motor cable.
2) Use a shielded cable for the sensor, etc., and ground the shield.
3) Install a noise filter in the cable which connects the controller to the robot.
