Switch from 7.5kw vfd to 700W vfd

Browse Source 
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
