21-32 Ext. 2 Maximum Reference
Default value: 100 ExtPID2Unit
Setup:
All setups
Data type: Int32
Set the value for parameter 21-32 Ext. 2 Maximum Reference before setting the values for the PID controller in parameter group
20-9* PID Controller.
Select the maximum reference for the closed-loop 1 controller. The dynamics of the PID controller depend on the value set in this
parameter. See also parameter 21-41 Ext. 2 Proportional Gain.
21-33 Ext. 2 Reference Source
Default value:
[0] No function
Setup: All setups
Data type:
Uint8
If feedback is not used, set its source to [0] No function. Parameter 20-20 Feedback Function determines how the PID controller
uses the 3 possible feedback.
This parameter defines which input on the drive should be treated as the source of the reference signal for the closed-loop 2 controller.
Analog input X30/11 and analog input X30/12 refer to inputs on the VLT® General Purpose I/O Card MCB 101.
