Controller optimization
Now the control loop of the axis can be closed. Before you should Save the
settings
(see page 97).
Then the axis can be switched into the preoperational mode (power-off) in order to
change then to closed loop operation. Switching between open and closed loop
operation is only possible in this state.
ATTENTION: When the control is activated, uncontrolled movements
of the axis may occur, if the control is inadequately parameterized!
ATTENTION: In order to limit the speed of the axis, the control signal
range for the valve control can be limited with the aid of the output
limitation. Settings: Optimization Output Chain X Upper Limit
bzw. Lower Limit. The limitation should not be set too small, as this
would put into effect an additional non-linearity (limitation) in the
distance, which complicates the controller alignment.

4.3.3.2 Signal filtering with external command value
In this chapter you can read about:
Signal filtering for external setpoint specification and electronic gearbox ....................... 103
Signal filtering for external setpoin
t specification and electronic cam.............................. 104
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:
