1) MR-J2S-350CP-S084 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-500CP-S084 or more
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 15.1.1 for details.
When using the regeneration converter or brake unit, connect it across P-N.
Do not connect it to the servo amplifier of MR-J2S-350CP-S084 or less.
Refer to Sections 15.1.2 and 15.1.3 for details.
Connect this terminal to the protective earth (PE) terminals of the servo motor
and control box for grounding.
