*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
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.
