MR-J4-22KGF4(-RJ)
The diagram shows MR-J4-22KGF4-RJ.
*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 Refer to the following for the power supply specification.
 Page 30 Servo amplifier standard specifications
*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 This is for MR-J4-_GF4-RJ servo amplifier. MR-J4-_GF4 servo amplifier does not have CN2L connector. When using MR-J4-_GF4-RJ
servo amplifier in the linear servo system or in the fully closed loop system, connect an external encoder to this connector. Refer to the
following and "Linear Encoder Instruction Manual" for the compatible external encoders.
