1) MR-J3-700T(4) or less
When not using the power factor improving DC reactor, connect P
When using the power factor improving DC reactor, disconnect P
power factor improving DC reactor to P
2) MR-J3-11KT(4) to 22KT(4)
MR-J3-11KT(4) to 22KT(4) do not have P
When not using the power factor improving reactor, connect P
When using the power factor improving reactor, connect it to P
Refer to section 14.11.
1) MR-J3-350T or less MR-J3-200T4 or less
When using servo amplifier built-in regenerative resistor, connect P( ) and D. (Factory-wired)
When using regenerative option, disconnect P( ) and D, and connect regenerative option to
P and C.
2) MR-J3-350T4 500T(4) 700T(4)
MR-J3-350T4 500T(4) and 700T(4) do not have D.
When using servo amplifier built-in regenerative resistor, connect P and C. (Factory-wired)
When using regenerative option, disconnect P and C, and connect regenerative option to P
and C.
3) MR-J3-11KT(4) to 22KT(4)
MR-J3-11KT(4) to 22KT(4) do not have D.
When not using the power regenerative converter and the brake unit, make sure to connect
the regenerative option to P and C.
Refer to section 14.2 to 14.5.
Supply the following power to L
Power supply
1-phase 200V to 230VAC, 50/60Hz
1-phase 100V to 120VAC, 50/60Hz
1-phase 380V to 480VAC, 50/60Hz
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 using the power regenerative converter/brake unit, connect it to P and N.
Do not connect to servo amplifier MR-J3-350T(4) or less.
For details, refer to section 14.3 to 14.5.
Connect to the earth terminal of the servo motor and to the protective earth (PE) of the control
box to perform grounding.
