Note 1. The battery (option) is used for the absolute position detection system in the position control mode.
2. 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.
3. Refer to the respective Instruction Manuals for the power supply specification.
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. For power supply specifications, refer to "MR-J4-_B_
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 the regenerative option, refer to Part 6 section 1.1 and 1.2.
