Using these input signals, the ”fixed speed setpoint” function can be selected with the required fixed set-
points 1 to 15, or the function can be canceled.

Note:
The ”fixed speed setpoint” function is described in Chapter 6.1.6.
If the function is canceled, an analog setpoint can be entered via terminals 56.x/14 and/or terminals
24.x/20.
In order to ensure that the function changes over in a controlled fashion (identified as being simulta-
neous) the switching operation of the inputs must be completed with one interpolation clock cycle
(P1010).
Refer to the ”status, fixed speed setpoint 1st to 4th input” output signal in Chapter 6.4.6.

STW2.3
The first speed setpoint filter is switched–in/switched–out using this input signal.
Important:
This function is only effective if the filter was parameterized using P1501:8 as lowpass filter (e.g. PT1).
Thus, the low–pass filter of the 1st speed setpoint filter can be disabled/enabled using this input signal,
which allows the speed setpoint to be smoothed.

Low–pass filter is disabled
0 signal
First speed setpoint filter is enabled

Low–pass filter is enabled
Note:
The status of the 1st speed setpoint filter is displayed using the ”first speed setpoint filter inactive” output
signal.
