P04.00
of motor 1
Description
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.
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 P03.10.
Range: 0–65535
Note: Set the value to 0 if motor parameter
autotuning is not performed.
Description
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)
Curves 2–4 are suitable for torque-variable load of
fan pump and similar equipment. You 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. You 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 in the figure below corresponds to
b
rated motor voltage, and f
motor frequency.
