Explanation of power supply system

Explanation of signals

• For the layout of connectors and terminal blocks, refer to the following.
Page 39 DIMENSIONS
L1/L2/L3 (Connection destination: Main circuit power supply)
Supply the following power to L1, L2, and L3. For 1-phase 200 V AC to 240 V AC power supply, connect the power supply to
L1 and L3. Leave L2 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
P+/C (Connection destination: Regenerative option)
If using the regenerative resistor built into the servo amplifier, connect the regenerative resistor to P+ and C (factory-wired).
MR-JET-10_ and MR-JET-20_ do not have a regenerative resistor.
If using a regenerative option, disconnect the lead wires of the built-in regenerative resistor from P+ and C. Then, connect the
regenerative option to P+ and C.
U/V/W (Connection destination: Servo motor power supply)
To prevent abnormal operation and malfunction, connect the servo amplifier power outputs (U/V/W) to the servo motor power
inputs (U/V/W) directly. Do not connect a magnetic contactor and others between them.
(Connection destination: Protective earth (PE))
Connect a servo amplifier to the grounding terminal of a servo motor and to the protective earth (PE) of a cabinet.
