autotuning
Automatic update will be performed after motor
parameter autotuning. In the closed-loop vector control
mode for synchronous motors, you can set the value of
this function code to P03.09.
Range: 0–65535
Note: Set the value to 0 if motor parameter autotuning
is not performed.

V/F curve setup of
motor 1
This group of function code defines the V/F curve of
motor 1 to satisfy different load characteristics needs.
0: Straight V/F curve; fit for constant-torque load
1: Multi-point V/F curve
2: Torque down V/F curve (power of 1.3)
3: Torque down V/F curve (power of 1.7)
4: Torque down V/F curve (power of 2.0)
Curve 2–4 are suitable for torque-variable load of fan
pump and similar equipment. Users can make
adjustment based on load characteristics to achieve
optimal energy-saving effect.
5: Customized V/F (V/F separation); under this mode, V
is separated from f. Users can adjust f through the
frequency reference channel set by P00.06 to change
the curve characteristic, or adjust V through the voltage
reference channel set by P04.27 to change the curve
characteristics.
Note: The V
b
in the figure below corresponds to rated
motor voltage, and f
b
corresponds to rated motor
frequency.
