Sinamics DCM - control field and armature circuit separately

Hi,

i want use Sinamics DCM 6RA8075-6DS22-0AA0-Z G00+S01 (210A armature 2Q, 15A field) to supply DC motor's on our testing bay.. We reparing DC Motors, and after that we must run motor, measuring, check vibrations, etc. We testing diffrent motors using 2 old DC Converter's (they slowly dying - analog converter, no spare parts, a lot of repairs)

I need to control armature circuit and field circuit separetly by 2 diffrent analog potentiometer.
Can i connect this two analog potentiometer to diffrent analog inputs in Advanced CUD, and in this way give setpoint to armature and setpoint to field circuit? Or i need two diffrent Sinamics DCM (one only for armature, and second only for field)?
I want to set specific current and voltage to every single circuit (armature and field) on motor by this two setpoint. It is possible?

Hello,

YES it is possible.

in this list manual you can find:

pag.2-603 to -605 CUD analog input

pag.2-645 main setpoint

pag.2-680 setpoint for field circuit control.
