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. A 1-phase 200 V AC to 240 V AC power supply may be used with the servo amplifier of MR-J4-70A-RJ or less. 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 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual".
3. Depending on the main circuit voltage and operation pattern, a bus voltage may drop, causing dynamic brake deceleration
during forced stop deceleration. When dynamic brake deceleration is not required, delay the time to turn off the magnetic
contactor.
4. Always connect between P+ and D terminals. When using the regenerative option, refer to section 11.2 of "MR-J4-_A_(-RJ)
Servo Amplifier Instruction Manual".
