NOTICE
This example assumes an induction motor is used, so P-20 Motor Construction = [0] Asynchron.
Function Parameter no. Setting
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using nameplate data. 1-2* As specified by motor name plate
Run Automatic Motor Adaptation (AMA). 1-29
[1] Enable complete AMAand then run the AMA
function.
2) Check that the motor is running in the right direction.
Run motor rotation check. 1-28 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 frequency converter and allowed application
operating specifications.
