When the servo motor runs with load, the allowable frequency will change according to the changes of
the load inertia and rotation speed. Use the following equation to calculate the allowable frequency.
Allowable fr equency =

The users can select the adequate external regenerative resistors according to the allowable frequency
by referring to the table below:
