Note 1. For the power supply specifications, refer to section 1.3.
2. The 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.
3. This is for the MR-J4-_A-RJ servo amplifier. The MR-J4-_A servo amplifier does not have the CN2L connector.
4. 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.
