Mitsubishi Electric MELSERVO-J4 Series Instruction Manual page 26

*1 Refer to the following for the power supply specifications.
Page 30 Servo amplifier standard specifications
*2 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.
*3 This is for MR-J4-_GF-RJ servo amplifier. MR-J4-_GF servo amplifier does not have CN2L connector.
*4 Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does not stop
immediately but coasts at an alarm occurrence for which the servo motor does not decelerate to stop. Ensure the safety in the entire
equipment. For alarms for which the servo motor does not decelerate to stop, refer to the following.

*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.
*6 The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake interlock) in [Pr.
PD07] to [Pr. PD09]. Failure to do so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs.
