Connection of regenerative option
If using the MR-RB50, MR-RB5N, MR-RB51, MR-RB5Z, MR-RB3M-4, MR-RB3G-4, MR-RB5G-4, MR-RB3Y-
4, or MR-RB5Y-4, cool it with a cooling fan. The cooling fan should be prepared by the customer.
For the wire sizes, refer to the following.
Page 217 Selection example of wires
The regenerative option generates heat that is 100 °C higher than the ambient temperature. Fully consider heat dissipation,
the installation position, wires used, and other relevant areas before installing the option. For wiring, use flame-retardant wires
or make the wires flame retardant, and do not let them touch the regenerative option. Use twisted wires with a maximum
length of 5 m for a connection with the servo amplifier.
For servo amplifiers of 7 kW or less
Remove the wiring between P+ and D and install the regenerative option between P+ and C. G3 and G4 are terminals for the
thermal sensor. Between G3 and G4 opens if the regenerative option overheats abnormally.
Remove the wiring between P+ and D.
