21-11 Ext. 1 Minimum Reference
Default value: 0 ExtPID1Unit
Setup: All setups
Data type: Int32
Select the minimum reference for the closed-loop 1 controller.
21-12 Ext. Maximum Reference
Default value:
100 ExtPID1Unit
Setup: All setups
Data type:
Int32
Set the value for parameter 21-12 Ext. 1 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 21-21 Ext. 1 Proportional Gain.
21-13 Ext. 1 Reference Source
Default value: [0] No function
