S120 CU322 PN infeed in STARTER? f30003

I am new with servo programming, did DCMs. In our project I do software and hardware is installed by other guys. We have servo configuration chosen by Siemensbased on the old servo configuration so power should be good.

We have:

1x SINAMICS CONTROL UNIT CU320-2 PN6SL3040-1MA01-0AA0

1x SINAMICS S120 DOUBLE MOTOR MODULE INPUT: DC 600V OUTPUT: 3-PH 400V, 9A/9A FRAME SIZE6SL31202TE210AA4

1x SINAMICS S120 SMART LINE MODULE INPUT: 3AC 380-480V6SL31306AE150AB1

2xSIMOTICS S SYNCHRONOUS MOTOR 1FK7-CT PN=1,9 KW1FK7062-xAF7x-xUxx

+ filter on input

(application with 2 manipulators which move cable spools)

I did DRIVE-CLIQ identification and downloaded objects to project, configured protocols to communication with S7-300 and it works but I can do max ~2000rpms & 50% acc/dec(without cargo) - otherwise fault of undervoltage f30003 when start or change few times direction - check supply etc. I checked internal VDC line and is set on 600VDC, really is 590VDC in stop and falls down to 430VDC when acc/dec). Tryed to do VDC control (kinetic and other but always fault). I am reading forums and started to check my topology, I am surprised that infeed module is not there! tryed to add this module manualy but there is no my catalog number 6SL31306AE150AB1, only 6SL31306TE21....

In addition I did commisioning steps in automatic controller setting (all 4 steps done succesfully) and tryed to do stationary measuring but alway fault of infeed;/

Please help me what I am doing wrong or what I dont do ;/ Dont know in which way to go ;) For any advices I will be very gratefull

greetings!

One sentence: The best Forum ever ;) Thank YouChristophD. When I connected infeed module like inManualCapter 4.8 then everything started work!
