Regenerative Option - Mitsubishi Electric MELDAS MDS-R Series Technical Specification And Instruction Manual

4-1 Regenerative option

For the regenerative option, always select a regenerative resistor unit or regenerative resistor in the
correct combination for each servo drive unit. Refer to "Appendix 2-2 Selecting the regenerative
resistor" for details on selecting the regenerative option.
The regenerative resistor generates heats, so wire and install the unit while taking care to safety. When
using the regenerative resistor, make sure that flammable matters, such as cables, do not contact the
resistor, and provide a cover on the machine so that dust or oil does not accumulate on the resistor and
ignite.
