(2) Simple Selection
Choose the appropriate regenerative resistor according to the allowable frequency and empty
load frequency in actual operation. The so-called empty allowable frequency is the frequency of
continuous operation when the servo motor runs from 0 r/min to the rated speed and then
decelerates from the rated speed to 0r/min within the shortest time. The following table lists the
allowable frequency when the servo drive runs without load (times/min).

When the servo motor runs with load, the allowable frequency will be different according to
different load inertia or speed. The following is the calculation method.
“m” represents load / motor inertia ratio.
