Description
Supply the following power to L1, L2, and L3. For 1-phase 200 V AC to 240 V AC,
connect the power supply to L1 and L3. Leave L2 open.
Servo amplifier
Power supply
MR-JE-10A to
MR-JE-70A
MR-JE-100A to
MR-JE-300A
3-phase 200 V AC to 240 V AC, 50
Hz/60 Hz
L1/L2/L3
1-phase 200 V AC to 240 V AC, 50
Hz/60 Hz

Power supply
P+/C/D
Regenerative
option
1) MR-JE-100A or less
MR-JE-10A to MR-JE-100A do not have D.
When using a servo amplifier built-in regenerative resistor, connect P+ and C.
(factory-wired)
MR-JE-10A and MR-JE-20A do not have a built-in regenerative resistor.
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) MR-JE-200A or more
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.
Refer to section 11.2 for details.
U/V/W
Servo motor
power output
Connect them to the servo motor power supply (U, V, and W). Connect the servo
amplifier power output (U, V, and W) to the servo motor power input (U, V, and W)
directly. Do not let a magnetic contactor, etc. intervene. Otherwise, it may cause a
malfunction.
N-
This is for manufacturer adjustment.
Leave this open.
MR-JE-10A to MR-JE-100A do not have N-.
Protective earth
(PE)
Connect it to the grounding terminal of the servo motor and to the protective earth
(PE) of the cabinet for grounding.
