DIMENSIONS.
Supply the following power to L1, L2, and L3. For 1-phase 200 V AC to 240 V AC of MR-JE-10B to
MR-JE-100B, connect the power supply to L1 and L3. Leave L2 open.
For 1-phase 200 V AC to 240 V AC of MR-JE-200B, connect the power supply to L1 and L2. Leave
L3 open.

1) MR-JE-100B or less
MR-JE-10B to MR-JE-100B do not have D.
When using a servo amplifier built-in regenerative resistor, connect it to P+ and C. (factory-
wired)
MR-JE-10B and MR-JE-20B do not have a built-in regenerative resistor.
When using a regenerative option, disconnect wires of the built-in regenerative resistor from P+
and C. Then, connect wires of the regenerative option to P+ and C.
2) MR-JE-200B 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 the terminals to the servo motor power supply terminals (U/V/W). Connect the servo
amplifier power output (U/V/W) to the servo motor power input (U/V/W) directly. Do not let a
magnetic contactor, etc. intervene. Otherwise, it may cause a malfunction.
This terminal is for manufacturer adjustment.
Leave this terminal open.
MR-JE-10B to MR-JE-100B do not have N- terminal.
MR-JE-200B and MR-JE-300B servo amplifiers without the N- terminal will be available
sequentially from the December 2016 production.
Connect this terminal to the grounding terminal of the servo motor and to the protective earth (PE)
of the cabinet for grounding.
