Always remove the wiring (across P-C) of the servo amplifier built-in regenerative resistor and fit the
regenerative option across P-C.
The G3 and G4 terminals act as a thermal sensor. G3-G4 is opened when the regenerative option
overheats abnormally.

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