Connect to the servo motor power supply terminals (U, V, W). During power-on, do
not open or close the motor power line. Otherwise, a malfunction or faulty may
occur.
When not using the power factor improving DC reactor, connect P
(Factory-wired.)
When using the power factor improving DC reactor, disconnect the wiring across

1) MR-J2S-350B or less
When using servo amplifier built-in regenerative resistor, connect between P
and 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-500B and 700B
MR-J2S-500B and 700B 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 12.1.1.
3) MR-J2S-11KB to 22KB
MR-J2S-11KB to 22KB do not have D terminal.
When not using the power supply return converter and the brake unit, make
sure to connect the regenerative option to P terminal and C terminal.
Refer to section 12.1.1.
When using return converter/brake unit, connect to P terminal and N terminal.
Do not connect to servo amplifier MR-J2S-200B or less.
For details, refer to section 12.1.2 to 12.1.3.
Connect this terminal to the protective earth (PE) terminals of the servo motor
and control box for grounding.
