Connecting a 2.2kW AC Motor with VFD Sako SKI780
Рет қаралды 27,932
Due to the incomming project of a CNC lathe for metal turning i did some test connections of this cheap chinese VFD.
VFD - Sako ski780 380V 2.2kW
AC Motor - 2.2kW 1410rpm Y 380V

Just purchased this mini vfd to use with my 2.2kw cnc spindle . Been making notes from your video (which is great by the way ) regards to parameter settings but would I be correct in saying that if I want to control it via my cnc motion controller, P0-02 should be set to 1 ?? I want to use 0 - 10v for speed ref ????
@GBWM_CNC 2 жыл бұрын
I'm glad my video helped! Exactly, you should use p0-02 = 1. I've got on my channel a video about setting up this VFD with MACH3 where I show the parameters I use for 0-10V control on this VFD

@@GBWM_CNC Hi there , thanks for your quick reply , unfortunately I’m using the smc5-5 offline controller but I think it’s similar to Mach 3 , Not entirely sure though !!! Thanks again for your help and info !!

@@davidwhite9676 I don't know that controller, but MACH3 uses 0-10V output too so the parameters on the VFD should be the same I guess. Good luck!

hey! Swietny filmik instruktazowy :D mam kilka pytan do ciebie co do tego falownika: 1 - czy uzywasz go i czy sie nadal sprawdza? 2 - czy rozwazales dolozenia brake resistor? 3 - przejrzalem pobierznie dokumentacje i nie widzialem wyjsc na dodatkowy moduł dla przycisku "emergency stop". Czy w urzadzeniu sa dodatkowe wyjscia na podlaczenie takiego przycisku? Dzieki za info!

Dziekuję! odpowiadając: 1 - używam w tokarce w moim warsztacie domowym i działa cały czas jak należy; 2 - nie rozważałem bo w moim przypadku akurat nie ma potrzeby; 3 - W mojej instrukcji, którą kiedyś gdzieś znalazłem widzę zapis, że do wejść DI1-5 można przypisać e-stop, który według instrukcji jest funkcją nr 47 czyli np. podłączając zgodnie z schematem sygnał z grzybka pod np. DI4 to trzeba by ustawić parametr p4-03 jako 47 i powinno działać pod wejściem DI4.

Hello. How to change the settings and start it remotely, not from the desktop?
@GBWM_CNC 2 жыл бұрын
Hello. Check out my video where I show how to setup this VFD for mach3. Mach3 is using a relay output which starts the vfd remotely. P0-02=1 is the parameter which allows you to control it by a terminal input.

Hello, thanks for this video ! Any idea why my vfd frequency doesn't go upper than 320hz, while it's supposed to go up to 500hz..?
@GBWM_CNC Ай бұрын
Maybe there is a upper limit parameter set to that value? Or you're using an analog voltage input less than max?

@@GBWM_CNC thanks for your fast answer ! The upper limit is that actual value that doesn't go upper than 320hz. Maybe a voltage problem... But what parameter to change then..?

Need to stop immediatelly, how to do? Is it capable to work for emergency stop? Maybe need a separate circuit for this function? Thanks :)

If I remember correctly it is possible to connect a e-stop to the vfd. But stopping immediatelly depends on the inertia you have to decelerate.

@@domenicofarina7125 You can try to read about vector and scalar control method in VFDs. I didn't try but there is a setting in this vfd to change the method. Vector control should provide more torque. But that's some theory I know from classes - got no experience. You can try to make some research - maybe changing the method might provide the little extra torque you need.

Oh man, is this a video of what you could do wrong when doing electrical installation ??? 1. NEVER drill the cables when crimping !!! 2. NEVER EVER use earth line (green/yellow) for anything other than earth potential !!!!! 3. Ground the motor properly !!! 4. Connect the calble at the motor connaction panel BELOW the U-brakets. Always use the left side of the screw, because then the rotation will pull the cable in, not out.
