listed in the parameters tables in order to operate the
VFD controller correctly. For troubleshooting, check

DISPLAY
In AUTO MODE, the following parameters will be
displayed on control display:
1. 30–60Hz is the output frequency to the motor.
Minimum factory set frequency allowed is 30 Hz.
2. 0.0 to Nominal Motor Amps. Maximum amps
draw is factory set, and it is set to nominal amp
draw of motor used.
3. 0.0-2.5 "WC is the actual reading from the pres-
sure transducer.
4. Located in the upper-right corner, the setpoint
value is displayed. It goes from 0% to 100%. That
is the actual setpoint for the controller. Setpoint
can be 0%, which is 0.0 "WC or 100%, which is
2.5 "WC.
Example:
20% corresponds to 0.5 "WC setpoint.
Setpoint can be updated using parameter 4011.
