Siemens Sinamics V20 Inverter Connection macro Cn007 in NPN mode?

(1/1)

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.

Looks like macro Cn002 should be fine in my application, since I've already found that potentiometer AI1 determines speed in this mode, DI1 can be used for ON/OFF1  8)
I do not need reverse motor spining direction, so Cn002 should be fine in NPN mode.

I've seen on YT examples with Cn007 macro used for something similar, so I thought to use Cn007, but probably Cn002 should be fine.
What do you think?

Kalin:
Changing the jumper DIC will change what voltage is sitting on the input terminals when they are open. If it is jumpered to 24V the terminals will have 24V on them and to change their state you would connect them to 0V.  This is what you are referring to as non and you can connect them in that configuration for 007

Yep, it makes sense.
Anyway I've found on YT desent example of using macro Cn002 with potentiometer and switch and this is exactly what I need.
PCB with low power 8bit 8pin MCU will be powered from 0V-10V potentiometer terminals since they provide a few mA of current and optocouplers used in NPN configuration to turn motor ON/OFF  :-/O
