7-2* Process Ctrl. Feedb.
"
Select which resources should be used for
feedback to the Process PID Control and how
this feedback should be handled.
7-20 Process CL Feedback 1 Resource
Option:
*
No function
Analog input 53
Analog input 54
Frequency input 29
Frequency input 33
Function:
It is possible to add up to two different feedback
signals to compose the actual feedback. This
parameter defines which input on the frequency
converter should be treated as the source
of the first feedback signal.
7-22 Process CL Feedback 2 Resource
Option:
*
No function
Analog input 53
Analog input 54
Frequency input 29
Frequency input 33
Function:
It is possible to add up to two different feedback
signals to compose the actual feedback. This
parameter defines which input on the adjustable
frequency drive should be treated as the source
of the first feedback signal.

How to Program
7-3* Process PID Ctrl.
"
Parameters for configuring the Process PID control.
*
It is possible to choose whether the process
control is to increase/reduce the output frequency.
This is done by having a difference between the
reference signal and the feedback signal.
*
It is possible to select whether the process control
is to continue regulating on an error even if it is not
possible to increase/reduce the output frequency.

When the start signal is given, the adjustable
frequency drive will react with a Speed control,
open loop following the ramp. Only when the
programmed start speed has been obtained
will it change to Process control.

times the error between the set point and the

feedback signal is to be applied.
