23.03 FixedSpeed2 (fixed speed 2)
FixedSpeed2 (23.03) is specifying a constant speed reference and overrides SpeedRef2 (2.01) at the speed
ramps input. It can be released by Jog2 (10.18) or MainCtrlWord (7.01) bit 9. The ramp times are set with
JogAccTime (22.12) and JogDecTime (22.13).

Since this speed offset is added after the speed ramp, it must be set to zero prior to stopping the drive.

23.06 SpeedErrFilt (filter for
∆
n)
Speed error (
∆
n) filter time 1. 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).

Idea of Window Control:
The idea of the Window Control is to block the speed controller as long as the speed error (
∆
n) remains within the window
set by WinWidthPos (23.08) and WinWidthNeg (23.09). This allows the external torque reference - TorqRef1 (2.08) - to
affect the process directly. If the speed error (
∆
n) exceeds the programmed window, the speed controller becomes active
and influences the process by means of TorqRef2 (2.09). To release window control set TorqSel (26.01) = Add and
AuxCtrlWord (7.02) bit 7 = 1.
This function could be called over/underspeed protection in torque control mode:
Note:
to open a window with a width of 100 rpm set WinWidthPos (23.08) = 50 rpm and WinWidthNeg (23.09) = -50 rpm.
23.08 WinWidthPos (positive window width)
Positive speed limit for the window control, when the speed error (
∆
n = n
ref
- n
act
) is positive.
