4.8. Parameter Group 7: Controllers

4.8.1. 7-** Controllers

Parameters group for configuring application controls.

4.8.2. 7-2* Process Ctrl. Feedb

Select feedback sources and handling for Process PI Control.

NB!

Set par. 3-15 to [0] No Function in order to use Analog Input as a feedback signal.

7-20 Process CL Feedback Resources

Option:

Function:

Select input to function as feedback signal.

[0]

*

No Function

[1]

Analog Input 53

[2]

Analog Input 60

[8]

Pulse Input 33

[11]

Local Bus Ref.

4.8.3. 7-3* Process PI Control

7-30 Process PI Normal/Inverse Control

Option:

Function:

[0]

*

Normal

Feedback larger than setpoint result in a speed reduction.

Feedback less than setpoint result in a speed increase.

[1]

Inverse

Feedback larger than setpoint result in a speed increase.

Feedback less than setpoint result in a speed reduction.

7-31 Process PI Anti Windup

Option:

Function:

[0]

Disable

Regulation of a given error will continue even when the output frequency cannot be increased/decreased.

[1]

*

Enable

PI-controller ceases from regulating a given error when the output frequency cannot be increased/decreased.

7-32 Process PI Start Speed

Range:

Function:

0.0 Hz

*

[0.0 - 200.0 Hz]

Until the set motor speed has been reached the frequency converter operates in Open Loop mode.

7-33 Process PI Proportional Gain

Option:

Function:

[0.01]

*

0.00 - 10.00

Enter the value for the P proportional gain, i.e. the multiplication factor of the error between the set point and the

feedback signal.

Note! 0.00 = Off.

7-34 Process PI Integral Time

Range:

Function:

9999.00 s

*

[0.10 - 9999.00 s]

The integrator provides an increasing gain at a constant error between the set point and the feedback signal. The

integral time is the time needed by the integrator to reach the same gain as the proportional gain.
