7.4 Motor Auto-tuning
You can obtain the parameters of the controlled motor through motor auto-tuning.
The motor auto-tuning methods are static auto-tuning 1, static auto-tuning 2 and dynamic auto-tuning. You can select a proper
auto-tuning method in F1-37.

3: Static auto-tuning 2
0
ƕ F1-37 = 0: The motor auto-tuning is not performed.
ƕ F1-37 = 1: Only the stator resistance, the rotor resistance and the leakage inductance are obtained through the static auto-
tuning 1.
ƕ F1-37 = 2: All the motor parameters are obtained through the dynamic auto-tuning. If the AC drive is in the CLVC mode, you
must make clear of the encoder parameters (F1-27 to F1-34).
ƕ F1-37 = 3: All the motor parameters are obtained through the static auto-tuning 2.
ƕ The three motor auto-tuning methods are compared as follows:
Auto-tuning Method Application Result
Static auto-tuning 1 It is applied to applications where the motor cannot be disconnected
from the load and dynamic auto-tuning is not allowed.
OK
Dynamic auto-tuning It is applied to applications where the motor
can be disconnected from the load.
Better
Static auto-tuning 2 It is applied to applications where the motor cannot be disconnected
from the load and dynamic auto-tuning is not allowed.
Best
Here takes the motor 1 (F0-24 = 0) as an example to describe the motor auto-tuning methods. If you need to perform motor 2 auto-
tuning, set F0-24 = 1 and refer to related parameters in group A2.

The static auto-tuning 1 process is as follows:
Steps Description
Step 1 Power on the AC drive. Set F0-02 = 0 to select the operation panel as the command source.
Step 2 Input the motor nameplate parameters (F1-00 to F1-05) correctly.
Step 3
Set F1-37 = 1 to select the static auto-tuning 1. Press
ENTER
on the operation
panel. The operation panel displays
.
Step 4
Press
RUN
on the operation panel.
The motor does not rotate but the motor get energized. The RUN indicates becomes ON.
After the preceding display disappears and the operation panel returns to the normal
parameter display state, it indicates that the auto-tuning is completed.
Parameters F1-06 to F1-08 are obtained.
