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, 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 MR-J4-_A_-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 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual" and "Linear Encoder
Instruction Manual" for the connectible external encoders.
Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo
amplifier may cause a malfunction.
POINT
Equipment other than the servo amplifier and servo motor are optional or
recommended products.
