Chapter 6 – Parameter Description [APP]
6-67
APP-10: High Limit Frequency for PID Control
APP-11: Low Limit Frequency for PID Control
This is the upper limit frequency at which the output
frequency is limited during PID control.
This is the lower limit frequency at which the output
frequency is limited during PID control.
APP-12: PID Output Scale
APP-13: PID P2 Gain
APP-14: P Gain Scale
This parameter sets the scale of PID controller output.
This parameter sets the second P-Gain for PID
control.
This parameter sets the conversion scale of P-Gain
and P2-Gain.
APP-15: PID Output Inversion
Parameter APP–15 [Output inversion] sets the PID
controller’s output polarity. The output can be direct
(No) or inverted (Yes).
Note: Most applications require (No), this means
as the pressure (or process variable) rises in the
system, the speed will fall. If this parameters is set
to (Yes), the speed will increase if the pressure (or
process variable) increases.
APP-17: PID Feedback U Adjustment
This feature can be useful for fan and pumps
application. It converts the linear pattern of a
feedback sensor to the squared pattern without any
additional settings.
