Function:
The FF factor sends a part of the reference signal around the PI controller which then only affects part of the control
signal.
By activating the FF factor less overshoot and high dynamics are gained when changing the setpoint.
This parameter is always active when par. 1-00 Configuration Mode is set to Process [3].
Function:
Enter the value for the On Reference Bandwidth.
The PI control error is the difference between setpoint and feedback and when this is less than the value set in this
parameter the On Reference is active.
