5.8.6 7-3* Process PID Ctrl.
Parameter 7-30 Process PID Normal/ Inverse Control
Table 462: Parameter 7-30 Process PID Normal/ Inverse Control
7-30 Process PID Normal/ Inverse Control
Default value: [0] Normal
Change during operation: True
Normal and inverse controls are implemented by introducing a difference between the reference signal and the feedback signal.
Set the process to increase the output frequency.
Set the process to decrease the output frequency.
Parameter 7-31 Process PID Anti Windup
Table 463: Parameter 7-31 Process PID Anti Windup
7-31 Process PID Anti Windup
Change during operation: True
Normal and inverse controls are implemented by introducing a difference between the reference signal and the feedback signal.
Continue regulation of an error even when the output frequency cannot be increased or decreased.
Cease regulation of an error when the output frequency can no longer be adjusted.
Parameter 7-32 Process PID Start Speed
Table 464: Parameter 7-32 Process PID Start Speed
7-32 Process PID Start Speed
Parameter type: Range, 0 - 6000 RPM
Change during operation: True
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.
Parameter 7-33 Process PID Proportional Gain
Table 465: Parameter 7-33 Process PID Proportional Gain
7-33 Process PID Proportional Gain
Parameter type: Range, 0 - 10
Change during operation: True
Enter the PID proportional gain. The proportional gain multiplies the error between the setpoint and the feedback signal.
