V/F curve setting of
motor 1
This group of function code defines the V/F
curve of motor 1 to meet the needs of different
loads.
0: Straight-line V/F curve, applicable to constant
torque loads
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 applicable to the torque loads
such as fans and water pumps. You can adjust
according to the characteristics of the loads to
achieve best performance.
5: Customized V/F (V/F separation); in this
mode, V can be separated from F and F can be
adjusted through the frequency setting channel
set by P00.06 or the voltage setting channel set
by P04.27 to change the characteristics of the
curve.
Note: In the following figure, V
b
is the motor
rated voltage and f
b
is the motor rated frequency.
