Par. no.
Setting
1) Make sure the motor runs properly. Do the following:
Set the drive to control the motor based on drive output fre-
quency.
0-02
Hz [1]
Set the motor parameters using nameplate data.
1-2*
As specified by motor name plate
Run Automatic Motor Adaptation.
1-29
Enable complete AMA [1] and then run the AMA function.
2) Check that the motor is running in the right direction.
Press the “Hand On” LCP key and the ^ key to make the
motor turn slowly. Check that the motor runs in the correct
direction.
If the motor runs in the wrong direction, remove power
temporarily and reverse two of the motor phases.
3) Make sure the frequency converter limits are set to safe values
Check that the ramp settings are within capabilities of the
drive and allowed application operating specifications.

Set up Analog Input 53 as Reference 1 Source.
3-15
Analog input 53 [1] (default)
6) Scale the analog inputs used for setpoint reference and feedback.
Scale Analog Input 53 for the pressure range of the potenti-
ometer (0 - 10 Bar, 0 - 10 V).

See Optimization of the PID Controller, below.
8) Finished!
Save the parameter setting to the LCP for safe keeping
0-50
