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 minimum external regeneration resistance of each driver. For
information on the minimum external regeneration resistance, refer to "Driver Regeneration Absorption Capacity"(P.4-39).
Safty Points
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 type of cover that enables heat dissipation.
