3.9.6 7-4* Advanced Process PID Ctrl.
7-40 Process PID I-part Reset
Option: Function:
[0] * No
[1] Yes Select Yes [1] to reset the I-part of the process PID controller. The selection will automatically revert
to No [0]. Resetting the I-part makes it possible to start from a welldefined point after changing
something in the process, e.g. changing a textile roll.
7-41 Process PID Output Neg. Clamp
Range: Function:
-100 %* [Application dependant] Enter a negative limit for the process PID controller output.
7-42 Process PID Output Pos. Clamp
Range: Function:
100 %* [Application dependant] Enter a positive limit for the process PID controller output.
7-43 Process PID Gain Scale at Min. Ref.
Range: Function:
100 %* [0 - 100 %] Enter a scaling percentage to apply to the process PID output when operating at the minimum
reference. The scaling percentage will be adjusted linearly between the scale at min. ref.
(par. 7-43
Process PID Gain Scale at Min. Ref. ) and the scale at max. ref. (par. 7-44 Process PID
Gain Scale at Max. Ref.
).
7-44 Process PID Gain Scale at Max. Ref.
Range: Function:
100 %* [0 - 100 %] Enter a scaling percentage to apply to the process PID output when operating at the maximum
reference. The scaling percentage will be adjusted linearly between the scale at min. ref.
(par. 7-43
Process PID Gain Scale at Min. Ref. ) and the scale at max. ref. (par. 7-44 Process PID
Gain Scale at Max. Ref.
).
7-45 Process PID Feed Fwd Resource
Option: Function:
[0] * No function Select which drive input should be used as the feed forward factor. The FF factor is added directly
to the output of the PID controller. This increases dynamic performance.
[1] Analog input 53
[2] Analog input 54
[7] Frequency input 29
[8] Frequency input 33
[11] Local bus reference
[20] Digital pot.meter
[21] Analog input X30-11
[22] Analog input X30-12
7-46 Process PID Feed Fwd Normal/ Inv. Ctrl.
Option: Function:
[0] * Normal Select Normal [0] to set the feed forward factor to treat the FF resource as a positive value.
[1] Inverse Select Inverse [1] to treat the FF resource as a negative value.
