Step Description
Step 3
Set F1-37 to 3 to select static auto-tuning on all parameters of the asynchronous
motor, and press Enter on the operating panel. The operating panel displays:
Step 4
Press the RUN key on the operating panel or SOP20. The motor does not rotate but
gets energized. The RUN indicator becomes ON.
After the preceding display disappears and the operating panel returns to normal
parameter display state, auto-tuning is completed.
Parameters F1-06 to F1-10 are obtained.
4.2.2 Auto-tuning of Synchronous Motor
Motor auto-tuning is the process by which the AC drive obtains the parameters of the controlled
motor.
The following auto-tuning methods are available for synchronous motors: static auto-tuning on some
parameters of synchronous motors, dynamic auto-tuning on all parameters of synchronous motors
with no load, and static auto-tuning on all parameters of synchronous motors.

Auto-tuning
0
0: No operation Auto-tuning is not performed.
11: Static auto-tuning
on some parameters of
synchronous motor
SVC, VVC: Auto-tuning is performed on only some
motor parameters, including the stator resistance,
axis D inductance, and axis Q inductance. The
motor does not rotate during auto-tuning.
12: Dynamic auto-
tuning on all
parameters of
synchronous motor
with no load
Ensure that the motor has no load during auto-
tuning.
SVC, VVC: Auto-tuning is performed on all motor
parameters, including the stator resistance, axis D
inductance, axis Q inductance, and back EMF. The
motor rotates during auto-tuning.
13: Static auto-tuning
on all parameters of
synchronous motor
SVC, VVC: Auto-tuning is performed on only some
motor parameters, including the stator resistance,
axis D inductance, and axis Q inductance. The
motor does not rotate during auto-tuning.
The auto-tuning effect is described as follows.
