1.4.2 Programming on Automatic Motor
Tuning (AMT)
Run AMT to optimise compatibility between the frequency
converter and the motor in VVC
•
The frequency converter 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 2 AMT modes for frequency converters.
