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.
(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.
Refer to section 11.2 to 11.5 for details.
Supply the following power to L11 and L21.
