2-2 Wiring Selecting the Sequence Input Method (Sink/Source Logic) „ Logic Selection Method for the Multi-function Input Terminals When the internal power supply is used, you can switch the logic by rearranging the short-circuit bar on the control circuit terminal block. The default setting is sink logic. 2 Design Note 1: Remove the short-circuit bar when the external power supply is used. 2-12 S1 SC PSC P24 PC S1 SC PSC P24 PC Short-circuit bar Short-circuit bar S1 SC PSC P24 PC S1 SC PSC P24 PC Inside the Inverter When interface power supply is used When external power supply is used Sink logic +V P24 Short-circuit PSC bar 24 V DC SC S1 S5 COM Output unit etc.
