Hello,
I've brand new Siemens Sinamics V20 Inverter:
https://www.automatyka.siemens.pl/docs/docs_ia/V20_ENG_2016.pdf 
Trying to figure out if is it possible use connection macro Cn007 in NPN mode similar to Cn002 by connecting DIC to 24V similar to product manual connection macro "Cn002 - Control from terminals PNP/NPN" ?

Unfortunatelly, connection macro "Cn007 - External push buttons with analog control" in product manual is shown in PNP mode where DIC wired to 0V, so while I'm designing optocoupled microcontroler based PCB with digital potentiometer and I'd like to controll 3phase 0.5kW inductor motor using this macro Cn007, NPN configuration shown in Cn002 macro could allow simply connect DI1,DI2,DI3,DI4 to 0V when needed.

Maybe someone had experience with this inverter and used Cn007 macro in NPN mode?
I'm confused, since in Cn002 macro thet implicit show PNP/NPN possible configurations, while in Cn007 macro only PNP is shown

Regards.
