Already switched earlier, now optimized code and connection plan to work best with new vfd (T130750W). Previous 7.5kw vfd will work too without using all 7 speed levels as at first. connection plan: changed pin assignment (1 free pin) Code: - vfd.cpp, main.cpp: remove not used D2 pin (only used with 7.5kw vfd) - config.hpp: change pin assignment
