Regenerative option selection
00: Regenerative option is not used.
For servo amplifier of 100 W, regenerative resistor is not used.
For servo amplifier of 0.2 kW to 7 kW, built-in regenerative
resistor is used.
Supplied regenerative resistors or regenerative option is used
with the servo amplifier of 11 kW to 22 kW.

82: MR-RB3G-4 (Cooling fan is required.)
83: MR-RB5G-4 (Cooling fan is required.)
84: MR-RB34-4 (Cooling fan is required.)
85: MR-RB54-4 (Cooling fan is required.)
91: MR-RB3U-4 (Cooling fan is required.)
92: MR-RB5U-4 (Cooling fan is required.)
FA: When the supplied regenerative resistors or the regenerative
option is cooled by the cooling fan to increase the ability with
the servo amplifier of 11 kW to 22 kW.
Connection of regenerative option
• When MR-RB50, MR-RB51, MR-RB5N, MR-RB3M-4, MR-RB3G-4, MR-RB5G-4, MR-RB34-4, MR-RB54-4,
MR-RB5K-4, or MR-RB6K-4 is used, a cooling fan is required to cool it. The cooling fan should be prepared
by the customer.
• For the wire sizes used for wiring, refer to the following. Page 400 Selection example of wires
The regenerative option generates heat of 100  higher than the ambient temperature. Fully consider heat dissipation,
installation position, wires used, etc. before installing the option. For wiring, use flame-resistant wires or make the wires flame-
resistant and keep them away from the regenerative option. Always use twisted cables of max. 5 m length for connection with
the servo amplifier.
