Parameter Number Parameter Name Default Value for Set-up 1 Default Value for Set-up 2 Parameter Description
20-21 Setpoint 1 15.0 150.0 Process setpoint. The
controller will adjust speed
to maintain this value.
20-00 Feedback 1 Source Analog Input 53 Analog Input 53 Feedback source for the
PID controller, transducer
input source.
20-12 Reference/Feedback Unit psi GPM Transducer feedback units
20-13 Min Reference/Feedb. 0.0 0.0 Minimum feedback value
for the transducer.
20-14 Max Reference/Feedb. 40.0 300.0 Maximum feedback value
for the transducer.
3-41 Ramp 1 Ramp Up Time 10 s 10 s Ramp up time (0 to full
speed). Increasing this
time will produce a slower
ramp up.
3-42 Ramp 1 Ramp Down Time 10 s 10 s Ramp down time (full
speed to 0). Increasing this
time will produce a slower
ramp down.
20-93 PID Prop Gain 5 5 Proportional correction
gain for PID controller.
Increasing this value will
produce a faster system
response. CAUTION:
Increasing this value too
high can make the system
unstable and produce
severe oscillations.
20-94 PID Integration Time 3.3 s 3.3 s Integration time for the PID
controller. Increasing this
value will produce a slower
system response.
CAUTION: Decreasing this
value too low can make the
system unstable and
produce severe oscillations.
22-80 Flow Compensation Disabled Disabled Enables or disables flow
compensation (head loss
compensation) function.
22-81 Square-Linear Curve
Approx.
100% 100% Adjusts shape of the flow
compensation control
curve.
22-84 Speed at No Flow [Hz] 0.0 Hz 0.0 Hz Speed required to maintain
the minimum head at no
flow. Use this parameter
when flow compensation is
enabled. See figure 3,
point A.
