Hello, Q2: see What is the meaning of the terms "sinking" (German: "P-schaltend") and "sourcing" (German: "M-schaltend") in digital modules of SIMATIC? Q1: now you know what PNP and NPN means to select PNP logic you connect DIC(Common) to 0V for NPN you connect DIC to +24V Regards, Marcjan |

Hi there. Marcjan essentially answered the question already.
I felt I should expand on the answer & highlight a connections with a sketch. (1)  "DI C" >> digital input common"0V" >> negative pole of the internal power supply "24V" >> positive pole of the internal power supply. You do not have to use the 24Vdc power supply that the drive supplies through the "24V" and "0V" connections. If you do use them, you can use them as the JPG shows you. If you are using an external power supply.. * source+ where you used to connect to pin "24V" * source- where you used to connect to pin "0V" * do not connect anything to pin "24V" *connect source- to pin "0V" or leave unconnected. (2) NPN - "negative switching" PNP - "positive switching" The choice for this comes in from the environment you are in.. * country (Europe - PNP, Japan - NPN) * (your) company * preference of electronics brand Each method has its own pros and cons. How do you want to switch the input off/on? * NPN is ON when signal is grounded to signal ground (source negative) * PNP is ON when signal is at source positive. Look again at the x2 options you have in the JPG.. which option describes your application the best?.. blue or yellow? I hope this is helpful. w |
