This i the simple explanation on how to wire the cheap Chinese VFD AT1 (single phase to 3-phase) so that it can be controller externally with a 10K potentiometer and a double pole double throw switch. Hope this helps
how can I adjust the torque of the motor at low frequency? I tried with parameter P70 but only get an ugly sound in the engine. I just can't understand what is written in the manual about this particular topic. I have the same inverter as you
Hi can you please help i have a cross cut saw and need to put in a two way switch so that i can have it running continuously or on the hand button stop&start also i need to put in an emergency stop
Hi Peter. Thanks for your video. I own a bench lathe (motor: three-phase, 1.1kw and 140rpm) and a VFD like yours. I would like to install a brake resistor, but I don't know if in this VFD I can install a brake resistor and what is the proper value. Please, could you help me. Thanks again and sorry, my English is not good.
Final i found that i had to set program P06 to 100Hz in order to cover 0-1500r/min using external potentiometer 10κΩ! At first i set 50Hz and with panel potent iometer i could change 0-1500 r/min but with an external potentiometer i changed 0-750r/min. So i set 100Hz to P06 it works 0-1500 r/min with external potentiometer 10 kΩ but when i change P10 to the panel potentiometer it works 0-3000 r/min
I want to use external analog signal for frequency and I used external potentiometer 10 kΩ but this external potentiometer start from 0 r/min until 760 r/min to the max position. My single phase motor works max 1500 r/min. Does anybody know what is wrong
Good video, but it only applies to the old AT1 models. This is no longer possible regardless of which supplier you bought it from. I bought from Banggood and Vevor. It's all the same crap. With the new models, when you set the parameters P10 to 2 and P11 to 2, you cannot achieve the set frequency (parameter P06) with the external potentiometer; you can only reach about half of the desired frequency. The operating instructions remain the same. So, you need to be careful about what you buy. Don't waste your money.
