[Appendix 1] Summary of MR-J4_B_-RJ020 + MR-J4-T20
Appendix 1-63
(2) MR-J4-700B-RJ020/MR-J4-500B4-RJ020/MR-J4-700B4-RJ020
Remove the wiring (between P+ and C) for the regenerative resistor built into the servo amplifier and
install the regenerative option between P+ and C. The G3 and the G4 terminals are thermal sensors.
Abnormal overheating of the regenerative option causes the contact between G3 and G4 to open.
Note 1. When using MR-RB51, MR-RB34-4, MR-RB54-4, MR-RB3G-4 and MR-RB5G-4,
perform forced cooling using the cooling fan (1.0
㎥
/min or more, 92 mm square).
2. Configure sequence of shutting off the electromagnetic contactor when abnormal
heating is caused.
Specifications for contacts between G3 and G4
Maximum voltage: 120 V AC/DC
Maximum current: 0.5 A/4.8 V DC
Maximum capacity: 2.4 VA
When you use the regenerative option, remove the wiring (between P+ and C) for the regenerative
resistor built into the servo amplifier, place back to back as shown in the diagram below and secure to
the frame using the supplied screw.
