(1) MR-J4-500B or less

Always remove the wiring from across P+ - D and fit the regenerative option across P+ - C. G3 and G4

are thermal sensor's terminals. Between G3 and G4 is opened when the regenerative option overheats

abnormally.

Servo amplifier

Always remove the lead from across P+ - D.

Cooling fan

(Note 1, 2)

Note 1. When using the MR-RB50 or MR-RB5N, forcibly cool it with a cooling fan (92 mm

× 92 mm, minimum air flow: 1.0 m

/min).

2. When the ambient temperature is more than 55 °C and the regenerative load ratio

is more than 60% in MR-RB30, MR-RB31, MR-RB32, or MR-RB3N, forcefully

cool the air with a cooling fan (1.0 m

/min or more, 92 mm × 92 mm) A cooling fan

is not required if the ambient temperature is 35 °C or less. (A cooling fan is

required to cool it within the range shown in the slash in the following figure. )
