11.2.4 Connection of regenerative option
POINT
When you use a regenerative option with an MR-JE-40B to MR-JE-100B,
remove the built-in regenerative resistor and wiring from the servo amplifier.
When MR-RB50 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 11.6.
A built-in regenerative resistor should not be mounted or removed frequently.
When you remount a built-in regenerative resistor, check the lead wires of the
built-in regenerative resistor for scratches or cracks.
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-retardant
wires or make the wires flame retardant and keep them away from the regenerative option. Always use
twisted cables of max. 5 m length for connection with the servo amplifier.
