par.
21-12 ExtPID1Unit]
Select the minimum for
the Closed Loop 1
Controller.

ExtPID1Unit]
Select
the maximum for the
Closed Loop 1 Controller.
The dynamics of the PID
controller will depend on
the value set in this
parameter. See also
21-21 Ext. 1 Proportional
Gain.
NOTE
Always set the desired value for 21-12 Ext. 1 Maximum
Reference before setting the values for the PID controller in
parameter group 20-9*.
21-13 Ext. 1 Reference Source
Option: Function:
This parameter defines 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 General Purpose I/O.
