VLT AutomationDrive FC 301/302
Programming Guide
5.8.7 7-4* Advanced Process PID Ctrl.
The following parameter is only available in FC 302:
-
Parameter 7-48 PCD Feed Forward
This parameter group is only used if parameter 1-00 Configuration Mode is set to [7] Extended PID speed CL or [8] Extended PID Speed
OL.
Parameter 7-40 Process PID I-part Reset
Table 471: Parameter 7-40 Process PID I-part Reset
7-40 Process PID I-part Reset
Default value: [0] No
Conversion index: –
Select the feedback source for the torque controller.
Option Name Description
[0]* No
[1] Yes Select [1] Yes to reset the I-part of the process PID controller. The selection automatically returns to [0] No. Re-
setting the I-part makes it possible to start from a well-defined point after changing something in the process,
for example changing a textile roll.
Parameter 7-41 Process PID Output Neg. Clamp
Table 472: Parameter 7-41 Process PID Output Neg. Clamp
7-41 Process PID Output Neg. Clamp
Default value: -100%
Conversion index: 0
Enter a negative limit for the process PID controller output.
Parameter 7-42 Process PID Output Pos. Clamp
Table 473: Parameter 7-42 Process PID Output Pos. Clamp
7-42 Process PID Output Pos. Clamp
Default value: 100%
Conversion index: 0
Enter a positive limit for the process PID controller output.
Parameter 7-43 Process PID Gain Scale at Min. Ref.
Table 474: Parameter 7-43 Process PID Gain Scale at Min. Ref.
7-43 Process PID Gain Scale at Min. Ref.
Default value: -100%
Conversion index: 0
Enter a scaling percentage to apply to the process PID output when operating at the minimum reference. The scaling percentage is
adjusted linearly between the scale at minimum reference (parameter 7-43 Process PID Gain Scale at Min. Ref.) and the scale at maxi-
mum reference (parameter 7-44 Process PID Gain Scale at Max. Ref.).
