Note: ATO VFD Cannot be used as a power source, it Can only be directly connected to an induction motor to control the motor speed.

Tips: What will the output torque be when the motor’s rotating speed changes?

Starting torque and maximum torque under the driving of VFD are smaller than those directly driven by power supply.
When the motor is powered by a power frequency supply, the starting and acceleration impact are huge. When the motor is powered by a VFD, the impact would be much weaker. Power frequency starting would produce a huge starting current. When a VFD is used, the output voltage and frequency of VFD are gradually added to the motor, so the starting current impact would be much smaller.

Practical VFD

I'm using this to adjust the speed of my farm machine, but I only know the basics and I'm having trouble trying to get it to work in closed loop. The main issue is that with P7.00=1 the pump starts and then very quickly goes to the maximum pressure it can achieve (0,37Mpa), then after time laps P7.35 the pump goes to 0Hz, and it never starts again. Even when the pressure in the pipe network goes below 0.2Mpa, it does not wake up. The b-15 reading seems to be the correct actual pressure, but the b-14 value is always the same as b-15. That is strange because it should never change, of course. When checking: The setting of P7.05 is still 0.3Mpa, while b-14 reads something like 0.2Mpa. My thoughts so far are going to put all parameters on factory default, by using P3.01=10, and then configure again. But I'd like to get technical help first, because there might be a simple solution. Another question: When the electrical power is interrupted, will the VFD then auto-start in closed loop again? If not, how can I prevent that every time the grid power goes off, I have to manually restart the VFD?
