Sink logic/source logic (When the inverter's internal power supply
is used)
Current flowing out turns control input terminals on. These are called sink logic terminals. (Type: -AN/-WN).
The general used method in Europe is source logic in which current flowing into the input terminal turns it
on (Typ: -WP).
Sink logic terminals and source logic terminals are sometimes referred to as minus common terminals and
positive common terminals, respectively.
Each logic is supplied with electricity from either the inverter's internal power supply or an external power
supply, and its connections vary depending on the power supply used.
