APPENDIX
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-_BF servo amplifiers in combination with HG series servo motors.
