Control circuit power supply
P, C, D Regenerative brake option
1) MR-J2S-350B or less
Wiring is factory-connected across P-D (servo amplifier built-in regenerative
brake resistor).
When using the regenerative brake option, always remove the wiring from
across P-D and connect the regenerative brake option across P-C.
2) MR-J2S-500B
MR-J2S-700B
Wiring is factory-connected across P-C (servo amplifier built-in regenerative
brake resistor).
When using the regenerative brake option, always remove the wiring from
across P-C and connect the regenerative brake option across P-C.
Refer to Section 12.1.1 for details.
N
Return converter
Brake unit
When using the return converter or brake unit, connect it across P-N.
Do not connect it to the servo amplifier of MR-J2S-350B or less.
Refer to Sections 12.1.2 and 12.1.3 for details.
Protective earth (PE)
Connect this terminal to the protective earth (PE) terminals of the servo motor
and control box for grounding.
