Description
This group of function code defines the
V/F curve of motor 2 to meet the needs of
different loads.
0: Straight-line V/F curve
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)
5: Customized V/F curve (V/F separation)
Note: Refer to the description for P04.00.
Note: Refer to the descriptions for P04.01
and P04.02.
Setting range of P04.14: 0.0%: (automatic);
0.1%–10.0%
Setting range of P04.15: 0.0%–50.0% (of the
rated frequency of motor 2)
Note: Refer to
P04.03–P04.08.
Setting range of P04.16: 0.00Hz– P04.18
Setting range of P04.17: 0.0%–110.0% (of the
rated voltage of motor 2)
Setting range of P04.18: P04.16– P04.20
Setting range of P04.19: 0.0%–110.0% (of the
rated voltage of motor 2)
Setting range of P04.20: P04.18– P12.02
(rated frequency of AM 2) or P04.18– P12.16
(rated frequency of SM 2)
Setting range of P04.21: 0.0%–110.0% (of the
rated voltage of motor 2)
The function code is used to compensate
for the motor rotating speed change
caused by load change in the space
voltage vector mode, and thus improve the
rigidity of the mechanical characteristics
of the motor. You need to calculate the
rated slip frequency of the motor as
follows:
-n*p/60
△f=f
