Parameter Setting; Connection Of Regenerative Option - Mitsubishi Electric MR-J4-10B(-RJ) Instruction Manual

11. OPTIONS AND PERIPHERAL 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, 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. Use twisted wires
with a maximum length of 5 m for a connection with the servo amplifier.

POINT
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 section 11.9.
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.
