Missing Enables & Faults at Starter for S110 CU305 PN

Dear Sirs,

I have a CU305 PN. I'm connected to it with starter. I also established a PN communication with s7-1200. Everything is fine about the communication part.

But I couldn't make the motor move at all. 

From Starter control panel, by activating "assume control priority" and "enable" I tried to move the motor with 1000rpm. When I started it, at diagnostics part, I had "30 speed controller inhibited error." After 1000ms monitoring time, the system said "The switch-on disable of the drive is active!" 

With that error pop-up, diagnostics part says lots of things :"OFF1, 2, 3 enable missing, operation enable missing, ramp function generator enable missing, ramp function generator start missing, setpoint enable missing, OFF2 enable internal missing, speed controller inhibited."

Control panel also says [45} Switching on inhibited - rectify fault, acknowledge fault, STO

Plus at Alarms page I have this error : 7802 : Drive infeed or power unit not ready

Servo is configured correctly : 1FK7063-2AF71-1QA0, encoder is also correct, AS20.

I have checked my motor & encoder cables.

I havent assigned any digital inputs or outputs to X130, X131, X132, X133. Should I assign some necessary IOs here?

Also r26 CO : DC link voltage smoothed parameter shows between 298V - 301V. Is this the problem?

P9 parameter is 0, Ready

What should I do?

Thanks for your attention.

DCN, DCP, R2 terminals are not connected.

r70 : CO : Actual DC Link Voltage : Changes between 292V - 323V but mostly 294V

Yes, 380VAC 3ph

Thank you.
