5: Continue running after insufficient torque is detected at constant speed
Insufficient torque is detected only in the constant speed operation process, and after the detection of insufficient
torque, the inverter continues to run.
6: Continue to run after insufficient torque is detected during operation
Insufficient torque is detected in the whole operation process, and the inverter continues to run.
7: Cut off the output after detecting insufficient torque at constant speed
Only in the process of constant speed operation, whether the torque is insufficient is detected, and after the insufficient
torque is detected, the inverter stops outputting, and the motor slides and stops freely.
8: Cut off the output after detecting insufficient torque during operation
After insufficient torque is detected in the whole running process, the inverter stops outputting and the motor slides and
stops freely.

As the starting torque of the motor is not enough, increasing the set value of 04.26 can increase the starting torque.
When the speed exceeds the set value of 04.25, the increased torque will slowly decrease to the given torque within the set
time of 04.27.

This set of function codes defines the V/F curve setting mode of the motor to meet different load characteristic
requirements. According to the definition of 05.00, you can choose five fixed curves and one custom curve.
0: linear curve
The linear curve is suitable for ordinary constant torque load, and the output voltage has a linear relationship with the
output frequency. See straight line 0 in figure F5-1.
1: torque reduction curve 1(1.3 power)
Torque reduction curve 1, the output voltage and output frequency are 1.3 power. See curve 1 in figure F5-1.
2: torque reduction curve 2(1.5 power)
Torque reduction curve 2, the output voltage and output frequency are 1.5 power. See curve 2 in figure F5-1.
3: torque reduction curve 3(1.7 power)
Torque reduction curve 3, the output voltage and output frequency are 1.7 power. See curve 3 in figure F5-1.
4: Square curve
The square curve is suitable for square torque loads such as fans and pumps to achieve the best energy-saving effect,
and the output voltage has a square curve relationship with the output frequency. See curve 4 in figure F5-1.
5: V/F curve set by user (determined from 05.01 to 05.06)
When 05.00 is selected as 5, the user can customize the V/F curve from 05.03 to 05.08, and define the V/F curve by
adding (V1, 01), (V2, F2), (V3, F3) and the polyline of origin and maximum frequency point, which is suitable for special
load characteristics. As shown in figure F5 -1.
