11. OPTIONS AND AUXILIARY EQUIPMENT
11 - 13
11.2.3 Parameter setting
Set [Pr. PA02] according to the option to be used.
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.

11.2.4 Connection of regenerative option
POINT
When the 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 sizes of wires used for wiring, refer to section 11.9.
The regenerative option generates heat of 100 °C higher than the ambient temperature. Fully consider heat
dissipation, installation position, used wires, etc. to place 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.
