11. OPTIONS AND PERIPHERAL EQUIPMENT
11 - 15
(2) MR-J4-500A4(-RJ)/MR-J4-700A(-RJ)/MR-J4-700A4(-RJ)
Always remove the wiring (across P+ to C) of the servo amplifier built-in regenerative resistor and fit the
regenerative option across P+ to C. G3 and G4 are thermal sensor's terminals. Between G3 and G4 is
opened when the regenerative option overheats abnormally.
Always remove the wiring (across P+ to C) of the
servo amplifier built-in regenerative resistor.

Note 1. When using the MR-RB51, MR-RB34-4, MR-RB54-4, MR-RB3U-4, or MR-RB5U-
4, forcibly cool it with a cooling fan (92 mm × 92 mm, minimum air flow: 1.0 m

).
2. Make up a sequence which will switch off the magnetic contactor when abnormal
heating occurs.
G3-G4 contact specifications
Maximum voltage: 120 V AC/DC
Maximum current: 0.5 A/4.8 V DC
Maximum capacity: 2.4 VA
When using the regenerative option, remove the servo amplifier's built-in regenerative resistor wires
(across P+ to C), fit them back to back, and secure them to the frame with the accessory screw as
shown below.
