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
