23.10 SpeedStep (speed step)
SpeedStep (23.10) is added to the speed error (
∆

values are limited by M1SpeedMin (20.02) and M1SpeedMax (20.02).

23.11 SpeedErrFilt2 (2
nd
filter for
∆
n)
Speed error (
∆
n) filter time 2. There are three different filters for actual speed and speed error (
∆
n):
−
SpeedFiltTime (50.06) is filtering the actual speed and should be used for filter times smaller than 30 ms.
−
SpeedErrFilt (23.06) and SpeedErrFilt2 (23.11) are filtering the speed error (
∆
n) and should be used for
filter times greater than 30 ms. It is recommended to set SpeedErrFilt (23.06) = SpeedErrFilt2 (23.11).
