Note 1. The built-in regenerative resistor is not provided for the MR-J4-10B-RJ010.
2. For 1-phase 200 V AC to 240 V AC, connect the power supply to L1 and L3. Leave L2 open.
For power supply specifications, refer to section 1.3.1.
3. Servo amplifiers MR-J4-70B-RJ010 or more have a cooling fan.
4. MR-J4 servo amplifier has P3 and P4 in the upstream of the inrush current suppression circuit. They are different from P1 and
P2 of MR-J3 servo amplifiers.
5. The power factor improving AC reactor can also be used. In this case, the power factor improving DC reactor cannot be used.
When not using the power factor improving DC reactor, short P3 and P4.
