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
plus
mode.
•
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.
Mode 1
1. Enter the main menu.
2.
Go to parameter group 1-** Load and Motor.
3. Press [OK]
4. Set motor parameters using nameplate data for
parameter group 1-2* Motor Data.
5.
Go to 1-29 Automatic Motor Tuning (AMT).
6. Press [OK].
7.
Select [2] Enable AMT
8. Press [OK].
9. The test runs automatically and indicates when it
is complete.
Mode 2
1. Enter the main menu.
2.
Go to parameter group 1-** Load and Motor.
3. Press [OK].
4. Set motor parameters using nameplate data for
parameter group 1-2* Motor Data.
5.
Go to 1-29 Automatic Motor Tuning (AMT).
6. Press [OK]
7.
Select [3] Complete AMT with Rotating motor
8. Press [OK]
9. The test will run automatically and indicate when
it is complete.
NOTICE!
In mode 2, the rotor rotates during the AMT progress.
No load should be added on motor in this AMT progress.
