Automatic motor tuning
Automatic motor tuning (AMT) measures stator
resistance R without the motor turning. This means
S
that the motor is not delivering any torque. AMT
can optimize adjustment of the adjustable frequency
drive to the motor. For best possible tuning, it is
recommended that AMT be performed on a cold
motor. Repeated AMT runs can cause motor heating,
resulting in an increase in the stator resistance. As
a rule, however, this is not critical. (See parameter
107, Automatic motor tuning, AMT, description
for more detail before running AMT.)
Perform AMT in accordance with the
following procedure:
1. Press the [QUICK MENU] key to enter
Quick menu mode
2. Use the [+] key to scroll to parameter 107.
3. In parameter 107, Automatic motor tuning,

4. Press [CHANGE DATA] and use the [+] key
to select data value [2], Optimization on (AMT

5. Press [START] key to activate AMT. "107" will
now flash and dashes will move from left to
right in the data value field.
6. When "107" appears once more with the data
value [0], AMT is complete. Press [STOP/RESET]
to save the motor data into the drive memory.
