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. When using servo amplifier 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.
6. For the network module connections, refer to the MR-J4-_TM_ Servo Amplifier Instruction Manual for each communication
method.
