Auto-Tuning for Permanent Magnet Motors
Automatically sets the V/f pattern and motor parameters E1-oo and E5-oo when a PM motor is used.

for Stator Resistance
T2-01 = 2
• Useful to tune the drive when the motor data were set up manually or by motor
code and the cable is longer than 50 m.
• Should also be performed if the cable length has changed after prior tuning.
YES
PM Rotational Auto-Tuning
T2-01 = 14
• A motor test report listing motor data is not available.
• Motor can be decoupled from the load and rotate freely while Auto-Tuning
is performed. Drive automatically calculates and sets motor parameters.
• PM Rotational Auto-Tuning gives more accurate results than Stationary
Auto-Tuning.

lists the data that must be entered for Auto-Tuning. Make sure the data is available before starting Auto-Tuning.
The necessary information is usually listed on the motor nameplate or in the motor test report provided by the motor
manufacturer. Also refer to page
for details on the Auto-Tuning process and selection.

Basic Auto-Tuning Preparations
• Auto-Tuning requires the user to input data from the motor nameplate or motor test report. Make sure this data is available
before Auto-Tuning the drive.
• For best performance, the drive input supply voltage must be at least equal to or greater than the motor rated voltage.
Note:
Better performance is possible when using a motor with a base voltage that is lower than the input supply voltage (20 V for 200 V class
models and 40 V for 400 V class models). This is particularly important when operating the motor above 90% of base speed, where high
torque precision is required.
