Note 1. 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.
2. Refer to section 1.3 for the power supply specification.
3. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that may cause the forced stop
deceleration to shift to the dynamic brake deceleration. When dynamic brake deceleration is not required, slow the time to turn
off the magnetic contactor.
4. This is for MR-J4-_A4-RJ servo amplifier. MR-J4-_A4 servo amplifier does not have CN2L connector. When using MR-J4-_A4-
RJ servo amplifier in the linear servo system or in the fully closed loop system, connect an external encoder to this connector.
Refer to Table 1.1 and "Linear Encoder Instruction Manual" for the compatible external encoders.
5. Always connect between P+ and D terminals. When using the regenerative option, refer to section 11.2.
