12: No‑load dynamic auto‑tuning
on all parameters of the
synchronous motor
It is applicable to scenarios where the motor can
be disconnected from the load.
Auto‑tuning is performed on the following motor
parameters in the FVC mode: F1‑06 (Motor stator
resistance), F1‑17 (Synchronous motor d‑axis
inductance), F1‑18 (Synchronous motor q‑axis
inductance), F1‑19 (Synchronous motor back
EMF), F1‑20 (Filter time constant), F1‑21
(Oscillation suppression gain), F1‑30 (Encoder
phase sequence), and F1‑31 (Encoder zero
position angle). Auto‑tuning is performed on the
following motor parameters in other modes:
F1‑06 (Motor stator resistance), F1‑17
(Synchronous motor d‑axis inductance), F1‑18
(Synchronous motor q‑axis inductance), F1‑19
(Synchronous motor back EMF), F1‑20 (Filter time
constant), and F1‑21 (Oscillation suppression
gain).
13: Static auto‑tuning on all
parameters of the synchronous
motor (excluding the encoder
installation angle)
This method is applicable to scenarios where the
motor cannot be disconnected from the load and
dynamic auto‑tuning on all parameters is not
allowed.
Auto‑tuning is performed on the motor
parameters including F1‑06 (Motor stator
resistance), F1‑17 (Synchronous motor d‑axis
inductance), F1‑18 (Synchronous motor q‑axis
inductance), F1‑20 (Filter time constant), and F1‑
21 (Oscillation suppression gain).
14: Synchronous motor inertia
auto‑tuning (only in FVC)
This method is applicable to scenarios that
requires fast dynamic response and that the load
must be connected during auto‑tuning.
Auto‑tuning is performed on the motor
parameters including F2‑35 (System inertia) and
F2‑36 (Motor and load inertia).
The following table compares the effects of these motor auto‑tuning methods.
