App. 4.3 Electrical Installation and configuration diagram
WARNING
CAUTION
The following shows representative configuration examples to conform to the IEC/EN/UL/CSA standards.
(1) 3-phase input
(2) 1-phase input
The connectors described by rectangles are safely separated from the main circuits described by circles.
Use MR-JE servo amplifiers in combination with HG series or HJ series servo motors.
Turn off the molded-case circuit breaker (MCCB) to avoid electrical shocks or
damages to the product before starting the installation or wiring.
Connecting a servo motor for different axis to U, V, W, or CN2 of the servo
amplifier may cause a malfunction.
Securely connect the cables in the specified method and tighten them with the
specified torque. Otherwise, the servo motor may operate unexpectedly.
