*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 (P.4-56).
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.
