Parameter Setting; Connection Of Regenerative Option - Mitsubishi MR-J4-10A Instruction Manual

11. OPTIONS AND AUXILIARY EQUIPMENT

11.2.3 Parameter setting

Set [Pr. PA02] according to the option to be used.

11.2.4 Connection of regenerative option

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.

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.

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.
