 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 4-4-2 Servo Drive
Regeneration Absorption Capacity on page 4-41.
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.
