Note
The equations provide an approximation and serve as estimate. The precondition is a
constant power range extending from the rated speed up to the maximum operating
speed.
You can calculate the acceleration time using the following program: Tool to calculate
the acceleration time

With the 200/250/257 A Motor Modules, the following motors achieve as maximum duty
type S6-40%:
1FE1106-4WN11, 1FE1125-4WN11, 1FE1125-4WP11, 1FE1126-4WN11, 1FE1126-
4WP11, 1FE1126-4WQ11;
The acceleration time does not change appreciably as a result.
