Signal filtering with external command value
In this chapter you can read about:
Signal filtering for external setpoint specification and electronic gearbox ........................233
Signal filtering for external setpoint specification and electronic cam ..............................234
The command signal read in from an external source (via HEDA or physical input)
can be optimized via different filters.
For this the following filter structure is available:

* Speed v and acceleration a are only present in the event of linear interpolation
(bus interpolator: O3925.1) if they are provided by an external source.
In quadratic or cubic interpolation, v and a are emulated.

Tracking filter
The displayed filter influences all outputs of the tracking filter.
Number
: Object number of the filter characteristic
Differentiator
Output signal = d(input signal)/dt
The output signal is the derivation (gradient) of the input signal
Filter
Number
: Object number of the filter characteristic
interpolation
500µs => 125µs
Interpolation
Linear Interpolation.
Values in the 500µs grid are converted into the more exact time
grid of 125µs.
