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 frequency =

m = load/motor inertia ratio
The users can select the adequate external regenerative resistors according to the
allowable frequency by referring to the table below:
