(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
2
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.

The comparison table of external regenerative resistor is provided below. Please choose the
appropriate regenerative resistor according to the allowable frequency.
The table below describes the suggested allowable frequency (times/min) of regenerative
resistor when the servo drive runs without load.
