(4) Connection of the regenerative option
POINT
When the MR-RB50 MR-RB51 MR-RB3M-4 MR-RB3G-4 MR-RB5G-4
MR-RB34-4
MR-RB54-4 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 11.11.
The regenerative option will cause a temperature rise of
100 relative to the ambient temperature. Fully
examine heat dissipation, installation position, used cables, etc. before installing the option. For wiring, use
flame-resistant wires and keep them clear of the regenerative option body. Always use twisted cables of
max. 5m length for connection with the servo amplifier.
