System Design
Combining External Regeneration Resistors
*1. Select a combination that has an absorption capacity greater than the average regeneration power
(Pr).
*2. Do not use a combination with resistance values lower than the allowable minimum regeneration
resistance of each drive. For information on the allowable minimum regeneration resistance, refer to
Servo Drive Regeneration Absorption Capacity on page 4-43.
Precautions for Safe Use
 Surface temperatures on regeneration resistance can reach 200°C.
Do not place objects that tend to catch fire nearby. To prevent people from touching them, install a
cover that enables heat dissipation.
