NOTICE
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
Option: Function:
This parameter denes which input
on the frequency converter should
be treated as the source of the
reference signal for the closed-loop
1 controller. Analog input X30/11
and analog input X30/12 refer to
inputs on the VLT
