6.4 Motor Auto-tuning
You can obtain parameters of controlled motor through motor auto-tuning.
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.

0
● F1-37 = 0: Motor auto-tuning is not performed.
● F1-37 = 1: Only stator resistance, rotor resistance and leakage inductance are obtained through
static auto-tuning 1.
● F1-37 = 2: All motor parameters are obtained through dynamic auto-tuning. If the AC drive is in FVC
mode, you must make clear of encoder parameters (F1-27 to F1-34).
● F1-37 = 3: All motor parameters are obtained through static auto-tuning 2.
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 motor cannot be disconnected from
load and dynamic auto-tuning is not allowed.
OK
Dynamic auto-tuning It is applied to applications where motor can be disconnected from load. Best
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.
Better
Motor 1 is used to describe motor auto-tuning methods below. If you need to perform motor 2 auto-
tuning, set F0-24 = 1 and refer to

F1-37 = 1: Static Auto-tuning 1
If V/F is adopted and motor cable exceeds 50 m, keep motor connected to load and use static
auto-tuning 1.
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 command source.
Step 2 Input motor nameplate parameters (F1-00 to F1-05) correctly.
Step 3
Set F1-37 = 1 to select static auto-tuning 1. Press
ENTER
on the operation panel. The
operation panel displays
.
Step 4
Press
RUN
on the operation panel.
Motor does not rotate but gets energized. The RUN indicator becomes ON.
After the preceding display disappears and the operation panel returns to normal
parameter display state, it indicates that auto-tuning is completed.
Parameters F1-06 to F1-08 are obtained.
