Note 1. The power factor improving DC reactor cannot be used.
2. For power supply specifications, refer to section 1.3.
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-_A1-RJ servo amplifier. MR-J4-_A1 servo amplifier does not have CN2L 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.
