1) MR-J2S-350CP or less
When using servo amplifier built-in regenerative resistor, connect between P-D
terminals. (Wired by default)
When using regenerative option, disconnect between P-D terminals and
connect regenerative option to P terminal and C terminal.
2) MR-J2S-500CP or 700CP
MR-J2S-500CP and 700CP do not have D terminal.
When using servo amplifier built-in regenerative resistor, connect P terminal
and C terminal. (Wired by default)
When using regenerative option, disconnect P terminal and C terminal and
connect regenerative option to P terminal and C terminal.
Refer to section 14.1.1 for details.
When using brake unit, connect to P terminal and N terminal.
Do not connect to servo amplifier MR-J2S-200CP or less.
For details, refer to section 14.1.2, 14.1.3.
Connect this terminal to the protective earth (PE) terminals of the servo motor
and control box for grounding.
