1.4.2 Programming on Automatic Motor
Tuning (AMT)
It is highly recommended to run AMT because it measures
the electrical characteristics of the motor to optimize
compatibility between the adjustable frequency drive and
the motor under VVC
•
The adjustable frequency drive builds a
mathematical model of the motor for regulating
output motor current thus enhancing motor
performance.
•
Run this procedure on a cold motor for best
results. To run AMT, use the numeric LCP (NLCP).
There are two AMT modes for adjustable
frequency drives.
