POINT
For the layout of connector and terminal block, refer to chapter 9 DIMENSIONS.
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.
When using 1-phase 200 V AC to 240 V AC for MR-JE-200A, connect the power supply to L1 and
L2. Leave L3 open.
Power supply
3-phase 200 V AC to 240 V AC,
50 Hz/60 Hz
1-phase 200 V AC to 240 V AC,
50 Hz/60 Hz
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.
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.
This is for manufacturer adjustment.
Leave this open.
MR-JE-10A to MR-JE-100A do not have N-.
Connect it to the grounding terminal of the servo motor and to the protective earth (PE) of the
cabinet for grounding.
