Change the igbt driver with IKCM30F60GA

[artayasa]

Hi sir, im interest with your project.
It is posible to change the igbtdriver with this chip, IKCM30F60GA. I see datasheet almost same.
And also this suport step/dir control??
If suport can i not use some things to save the space?? I just want to used ac servo pmsm with abz encorder 2500ppr.

Pinout is the same so should work, overcurrent limit could be set higher because igbt's are 30A max instead of 20A. Thermally i think it would perform similarly.

Positioning control mode and step/dir input is not implemented yet, only speed/torque control.

On second look NTC pin does not exist so igbt temperature would not work and 2 power supply pins are not there you would have to bend following pins 2 holes forward

It posible to add step dir i terface sirr? I very interst for that, because i want to used for cnc sir, thank you

What do u mean sir??? Mybei will used external ntc sirr

For now step dir are apply sir? Because i see demo cnc with grbl, i think it control by step/dir??

I made some progress but it's still buggy, and needs hardware modification on board. czw., 18 lip 2024, 22:03 użytkownik artayasa ***@***.***> napisał:

Owhh okee sirr, and also i have more ex broken ac servo drive in home, i will modify it to used your frimeware and coustem the board. But to hard buy curent shunt G010SME-SP3. It posible to used acs712?? Without curent aplifier?? Because all ofthat i have already. And my servo is 2pcs 100v, 5 pcs 200v. How do u control the voltage? By software??

And also about the software where i can get it?? I dont see in your github. Thank u for the great project.
