Re: AUDI A4 B5 conversion to 135 volts
Thanks. I'll compare it with my own. Two questions: Why are the specified values of sincosofs here? What is the firmware version? I see that it's old, but what is it? I had 5.20 sinus used and I didn't have the parameter of the maximum phase current. sincosofs is selected for a soft start of the en...

Re: PWM OUT! the output for the tachometer, how to set it up correctly? Is it possible?
and here is the second device on stm32, I almost wrote the program code, it remains to debug a little, the problem is that the tachometer sometimes jumps, I'll deal with it later

I made the first device on arduino, I can put all the material on it here, the minus is that it does not always read can, I am currently developing the second device on stm32

hi. I also ran into such a problem on my Audi a4, I put together a device that listens to can and translates into a meander with a frequency that varies depending on the RPM

Re: Windind change ACIM industrial motor + inverter note-e power
I also had something similar, most likely the modules do not pull current. How do you have the engine turned on in a star or in a triangle?

In one housing inverter and motor capacity of 160 kilowatts
Нi. There is a factory inverter with an IPM engine with a capacity of 160 kilowatts. Everything is built into one housing, which is convenient for installation in a car. My friend asked me for help with starting the inverter, it works through the can bus. There is a document with can messages, someo...

Re: AUDI A4 B5 conversion to 135 volts
I opened the inverter, and I could not find a drop of water in it, one of my friends said that there might not be enough capacitance of capacitors in the inverter, when the cold increases the load

Re: Windind change ACIM industrial motor + inverter note-e power
Controller with 12 mosfet IRFP4668, so the voltage will not be raised, they are only 200 volts.
I will publish the settings file later
