Process Pid Ctrl - Danfoss VLT AutomationDrive FC 301 Programming Manual

Programming Guide | VLT® AutomationDrive FC 301/FC 302

7-3* Process PID Ctrl.

6.9.6
7-30 Process PID Normal/ Inverse Control
Default value: [0] Normal
Setup: All setups
Data type: Uint8
Normal and inverse controls are implemented by introducing a difference between the reference signal and the feedback signal.
Option Name
[0]* Normal
[1] Inverse
7-31 Process PID Anti Windup
Default value: [1] On
Setup: All setups
Data type: Uint8
Normal and inverse controls are implemented by introducing a difference between the reference signal and the feedback signal.
Option Name
[0] Off
[1]* On
7-32 Process PID Start Speed
Default value: 0 RPM
Setup: All setups
Data type: Uint16
Enter the motor speed to be attained as a start signal for commencement of PID control. When the power is switched on, the drive starts
to ramp and then operates under speed open-loop control. When the process PID start speed is reached, the drive changes to process
PID control.
7-33 Process PID Proportional Gain
Default value:
0.10
Setup: All setups
Data type:
Uint16
Enter the PID proportional gain. The proportional gain multiplies the error between the setpoint and the feedback signal.
