0: No auto‑tuning Motor auto‑tuning is disabled.
11: Static auto‑tuning on
partial parameters of
synchronous motor (back
EMF is not auto‑tuned)
SVC and PMVVC: Auto‑tuning is performed on partial motor
parameters, including stator resistance and DQ shaft
inductance. The motor does not rotate during auto‑tuning.
FVC: Auto‑tuning is performed on partial motor
parameters, including stator resistance, DQ shaft
inductance, and encoder zero position angle. If a resolver
or 23‑bit encoder is used, the motor does not rotate during
auto‑tuning. If an ABZ encoder is used, the motor rotates
for a short period of time during auto‑tuning.
12: No‑load dynamic auto‑
tuning on all parameters
of synchronous motor
The motor must be disconnected from load during auto‑
tuning.
SVC and PMVVC: Auto‑tuning is performed on all motor
parameters, including stator resistance, DQ shaft
inductance, and back EMF. The motor rotates during auto‑
tuning.
FVC: Auto‑tuning is performed on all motor parameters,
including stator resistance, DQ shaft inductance, back
EMF, encoder zero position angle, and encoder phase
sequence. The motor rotates during auto‑tuning.
13: Static auto‑tuning on
all parameters of
synchronous motor
SVC, PMVVC and FVC: Auto‑tuning is performed on partial
motor parameters, including stator resistance and DQ
shaft inductance. The motor does not rotate during auto‑
tuning.
The following table compares the effects of these motor auto‑tuning methods.
Table 3–9 Motor auto‑tuning methods
Auto‑tuning Method Applicable Scenario
Effect
Static auto‑tuning on partial
parameters of synchronous motor
The motor cannot be disconnected from load and dynamic
auto‑tuning is not allowed.
After auto‑tuning, manually set the back EMF (SVC and
PMVVC) and encoder phase sequence.
Better
No‑load dynamic auto‑tuning on all
parameters of synchronous motor
This method is applicable to scenarios where the motor can
be easily disconnected from the application system.
Best
Static auto‑tuning on all parameters of
synchronous motor
The motor cannot be disconnected from load and motor
rotation is not allowed.
After auto‑tuning, manually set the back EMF (SVC and
PMVVC), encoder zero position angle (FVC), and encoder
phase sequence (FVC).
Good
In addition to the preceding three auto‑tuning methods, you can also input motor
parameters manually.
In addition to using the LED panel as the command source for motor auto‑tuning, you
can also use an external LCD panel (set F0‑02 to 0), DI terminals (set F0‑02 to 1) or
