The above configuration example is for MR-J4-11KB or models
with more capacity.
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 8
section 1.1 or 1.2.

Note 1.When not using the STO function in MR-J4-_B_, attach a short-circuit connector supplied with a servo amplifier onto CN8
(STO input signal connector).
2.The configuration of the main circuit terminal block differs depending on capacity. Refer to "Part 6: Common Reference Material".
