1) MR-J2S-350B or less
When using servo amplifier built-in regenerative brake resistor, connect
between P-D terminals. (Wired by default)
When using regenerative brake option, disconnect between P-D terminals and
connect regenerative brake option to P terminal and C terminal.
2) MR-J2S-500B 700B
MR-J2S-500B and 700B do not have D terminal.
When using servo amplifier built-in regenerative brake resistor, connect P
terminal and C terminal. (Wired by default)
When using regenerative brake option, disconnect P terminal and C terminal
and connect regenerative brake 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-350B 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.
