Default
Explanation
P3-01
Proportional Gain
0.1 to 30.0
-
2.0
PID Controller Proportional Gain.
Higher values provide a greater
change in the drive output
frequency in response to small
changes in the feedback signal.
Too high a value can cause
instability.
P3-02
Integral Time Constant
0.0 to 30.0
Seconds
1.0
PID Controller Integral Time.
Larger values provide a more
damped response for systems
where the overall process
responds slowly.
P3-03
Differential Time
Constant
0.00 to 1.0
Seconds
0.00
PID Differential Time Constant
P3-04
PID Operating Mode
0: Direct
1: Inverse
-
0
Direct operation – Motor speed
increases with an increase in the
feedback signal
Inverse Operation – Motor speed
decreases with an increase in
the feedback signal.
P3-05
PID Set Point /
Reference Select
0: Digital
1: Analog
-
0
Selects the source for the PID
Reference / Setpoint
0: P3-06 is used
1: Bipolar analog input is used
P3-06
PID Digital Reference
0.0 to 100.0
%
0.0
Sets the preset digital PID
reference / set point.
P3-07
PID controller high limit
output
P3-08 to 100.0
%
100
Limits the maximum value
output from the PID controller.
P3-08
PID Controller Low
Limit Output
0 to P3-07
%
0
Limits the minimum output from
the PID controller
P3-09
User PID Output Limit /
Function Control
0: Digital output limits
1: Analog Upper Limit
2: Analog Lower Limit
3: PID added to Bipolar analog
input reference
-
0
0: PID output range limited by
P3-07 & P3-08
1: PID maximum output limited
by the signal applied to the
bipolar analog input
2: PID minimum output limited
by the signal applied to the
bipolar analog input
3: PID output is added to the
speed reference applied to
the bipolar analog input
P3-10
PID Feedback Source
Select
0: 2nd Analog Input
1: Bipolar analog input
-
0
Selects the source of the PID
feedback signal.
