Sink logic/source logic (When inverter's internal power supply is used)

Current flowing out turns control input terminals on. These are called sink logic terminals.

The method generally used in Europe is source logic in which current flowing into the input terminal turns it on. Sink logic terminals and source logic terminals are sometimes referred to as negative logic terminals and positive logic terminals, respectively.

Each logic is supplied with power from either the inverter's internal power supply or an external power supply, and its connections vary depending on the power supply used.
