Page 30 Servo amplifier standard specifications
*2 Servo amplifiers MR-J4-200GF4(-RJ) or more have a cooling fan.
*3 MR-J4 servo amplifier has P3 and P4 in the upstream of the inrush current suppression circuit. They are different from P1 and P2 of MR-
J3 servo amplifiers.
*4 This is for MR-J4-_GF4-RJ servo amplifier. MR-J4-_GF4 servo amplifier does not have CN2L connector.
*5 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.
