14. OPTIONS AND AUXILIARY EQUIPMENT
(3) Parameter setting
Set parameter No.PA02 according to the option to be used.
Selection of regenerative option
00: Regenerative option is not used
For servo amplifier of 100W, regenerative resistor is not used.
For servo amplifier of 200 to 7kW, built-in regenerative resistor is used.
Supplied regenerative resistors or regenerative option is used with
the servo amplifier of 11k to 22kW.

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 14.9.
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 cables and keep them clear of the regenerative option body. Always use twisted cables of
max. 5m length for connection with the servo amplifier.
