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:
2020.6 speed
2011.1 2011.2
2020.1

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

Number: Object number of the filter characteristic
Interpolation
Linear Interpolation.
Values in the 500µs grid are converted into the more exact time
interpolation
grid of 125µs.
500µs => 125µs
Note:
The objects 2020.6 and 2020.7 are status values, which can be used for control
purposes in the IEC program.
The objects 680.12, 681.4 and 682.4 are input characteristics which can also be
found in the controller structure.
A command jerk setpoint generator is not required for an external command
value.
The description of the objects can be found in the object list.
