11.2.4 Connection of regenerative option

POINT

When the MR-RB50, MR-RB51, or MR-RB5N 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.
