Function
1) Make sure that the motor runs properly. Do the following:
Set the motor parameters using nameplate data.
Run Automatic Motor Adaptation.
2) Check that the motor is running in the right direction.
Run Motor Rotation Check.
3) Make sure that the frequency converter limits are set to safe values
Check that the ramp settings are within capabilities of
the drive and allowed application operating specifi-
cations.
Prohibit the motor from reversing (if necessary)
Set acceptable limits for the motor speed.
Switch from open loop to closed loop.
4) Configure the feedback to the PID controller.
Select the appropriate reference/feedback unit.
5) Configure the set-point reference for the PID controller.
Set acceptable limits for the set-point reference.
Choose current or voltage by switches S201/S202
6) Scale the analog inputs used for set-point reference and feedback.
Scale Analog Input 53 for the pressure range of the
potentiometer (0–10 Bar, 0–10 V).
Scale Analog Input 54 for pressure sensor (0–10 Bar, 4–
20 mA)
7) Tune the PID controller parameters.
Adjust the closed loop controller, if needed.
8) Finished!
Save the parameter setting to the LCP for safe keeping

As specified by motor name plate
[1] Enable complete AMA and then run the AMA
function.
If the motor runs in the wrong direction, remove
power temporarily and reverse two of the motor
phases.
