When not using the power factor improving DC reactor, connect P3 and P4(factory-wired).
When using the power factor improving DC reactor, disconnect P3 and P4, and connect the
power factor improving DC reactor to P3 and P4.
Refer to section 11.11 for details.
P+/C/D Regenerative option
(1) 200 V class
1) MR-J4-500A(-RJ) or less
When using a servo amplifier built-in regenerative resistor, connect P+ and D (factory-
wired).
When using a regenerative option, disconnect P+ and D, and connect the regenerative
option to P+ and C.
2) MR-J4-700A(-RJ) to MR-J4-22KA(-RJ)
MR-J4-700A(-RJ) to MR-J4-22KA(-RJ) do not have D.
When using a servo amplifier built-in regenerative resistor, connect P+ and C (factory-
wired).
When using a regenerative option, disconnect wires of P+ and C for the built-in
regenerative resistor. And then connect wires of the regenerative option to P+ and C.
(2) 400 V class
1) MR-J4-350A4(-RJ) or less
When using a servo amplifier built-in regenerative resistor, connect P+ and D. (factory-
wired)
When using a regenerative option, disconnect P+ and D, and connect the regenerative
option to P+ and C.
2) MR-J4-500A4(-RJ) to MR-J4-22KA4(-RJ)
MR-J4-500A4(-RJ) to MR-J4-22KA4(-RJ) do not have D.
When using a servo amplifier built-in regenerative resistor, connect P+ and C. (factory-
wired)
When using a regenerative option, disconnect wires of P+ and C for the built-in
regenerative resistor. And then connect wires of the regenerative option to P+ and C.
