Notes:
1. Refer to "MR-J2S SERVO AMPLIFIER INSTRUCTION MANUAL" for details.
2. This is for the motor with an electromagnetic brake. The polarity of the power supply connected to the electromagnetic brake is irrelevant.
A separate connector from the motor power supply connector is prepared as an electromagnetic brake connector for the HC-SFS121B to 301B, 202(4)B to 702(4)B, 203B, 353B,
HC-LFS202B, 302B, HC-UFS202B to 502B motors.
3. For grounding, connect the ground wire to the control box’s protection ground terminal via the servo amplifier’s protection ground (PE) terminal.
