QSINK (Negative) logic/SOURCE (Positive) 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 is sometimes referred to as negative logic, and source logic is referred to as positive logic. 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.
