Programming Guide
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
Conversion index: –
Normal and inverse controls are implemented by introducing a difference between the reference signal and the feedback signal.
Option Name
[0]* Normal
[1] Inverse
Parameter 7-31 Process PID Anti Windup
Table 463: Parameter 7-31 Process PID Anti Windup
7-31 Process PID Anti Windup
Default value: [1] On
Conversion index: –
Normal and inverse controls are implemented by introducing a difference between the reference signal and the feedback signal.
Option Name Description
[0] Off Continue regulation of an error even when the output frequency cannot be increased or decreased.
[1]* On 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
Default value: 0 RPM
Conversion index: 67
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
Default value: 0.10
Conversion index: -2
Enter the PID proportional gain. The proportional gain multiplies the error between the setpoint and the feedback signal.
