Run AMT to optimize compatibility between the drive and the motor in VVC
+
mode.
The 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 2 AMT modes for drives.
