Re: Gen 3 inverter converter control software

Hello everyone! Anyone have any success in getting data from atmega to wemos via the web interface? Atmega sends data to the port monitor, wemos sends the "params" command correctly and it is visible in pytty. I connect uart esp and atmega - there are no parameters in the web interface ......

Fine! It worked for me. Good news! Just the one line of code needed? Added this line: #include <ESP8266WiFi.h> and this is: #ifdef WIFI_IS_OFF_AT_BOOT enableWiFiAtBootTime(); // can be called from anywhere with the same effect #endif https://arduino-esp8266.readthedocs.io/en/latest/esp8266wifi/gene...

It might be an easy fix but I don't have any hardware on hand to test right now.

I experimented with two Leaf inverters with Johannes boards version 3.

Re: Mainboard V3 FAQ

Ты чего-то явно не замечаешь. Принцип построения наверное всех 3-х фазных преобразователей частоты одинаков. С микроконтроллера выходит 6 выводов управления фазами, По 2 на фазу - один вывод управляет ключом задающим положительный потенциал на фазе - второй отрицательным потенциалом. И так в каждой ...

Нет - С тремя выводами никак работать не может, только 6 выводов. 3 на верхнее плечо и 3 на нижнее плечо. PWM1,2,3 BOT - нижнее плечо фаз, ты его не подключил на изображении. PWM1,2,3 TOP - это верхнее плечо - оно у тебя схематически подключено. No - It can’t work with three conclusions, only 6 conc...

Re: engines DA-90S slavynka

I'd configure it like a normal 6-pole motor (polepairs=3). If run at nominal voltage (how much?) fweak would be around 1500/60*3=75Hz. EDIT: if I understand right the slavynka motor offers no advantage over a normal wound motor when run with an inverter. Переведу: комбинированная обмотка типа "...

So they need to be calibrated after final installation on the phase conductor. Selecting the values of il1gain and il2gain leading to the value of the test ammeter - I understand correctly?
