2.5 Wiring and Cable Connection
The following shows the wiring and cable connection example for the Simple Motion module and servo amplifiers.
The system below uses the cables for MR-J4-10B. If the capacity of the servo amplifier is different, refer to SERVO
AMPLIFIER INSTRUCTION MANUAL for each model.
1. Wiring for power supply module
The following shows an example when a power wire and a grounding wire are connected to the power supply module.
Connect an isolation transformer when noise often enters in the power supply system.
2. Wiring for servo amplifier power supply and servo motor power cables
Wire the control circuit power supply (L11, L21) and the main circuit power supply (L1, L2, L3) of the servo amplifier, and the
servo motor power cable.
