Drives status remained green I

Hi

I have a kuka KRC2 ed 2005 KR 210 and today when I switched on the controller I had some erros as in the photos.
Whatever I tried drives status I remain green . Robot dont move.
I used for first errors SafeOperation Configuring in Setup and they were removed as in Safe Robot 1.1 manual.
But no change in green I.
I even reinstalled KSS 5.5.15 but after reboot still I remain green , and emergency stop.
Finally the errors are software limit switch +A2 but my axis 2 is almost in home postion, couldn't reach any limit.As in the third photo.
Last photo is taken from RDC, where there are two flashing red leds.
My robot is Safe Robot.

I observed also a message while initialising messages appear but not remained permanent, it was flasing 306 Selection Active, but don't reamain . Even no program was selected.

Any suggestion ?

Untill yesterday robot worked normally and no reconfiguring was made, neither in mada nor in config.dat

The only one matter is that Drives status I remain green as for active selection. And robot is blocked in emergency stop.
After start initialization with message Safe RDC state confirmed, so everything is ok on safety check, is flashing message
306 Selection active, ...appear, disappear, three, four times than no more. Is clear.
When I try to select sps.sub get the message selection active 306

Thank you for correcting Spiral, but any ideea what could be the cause?
Is possible to be KPS 600?
I reinstalled KSS 5.5.15 and no change, I still green.

I tried with other KCP, same problem. Drives status I still green.
You mean safety board, ESC ?

X 11 is ok.
Any other ideea?

Thank you all.
PanicMode, I wear with me SafeOperation manual 2.1
Of course I read remedy for 411 and other initial messages.
The problem is that whatever I did I status drive remain green and blocked.
The only messages I have now Is safety mode not possible and limit switch +A2 (but axis 2 is almost in zero mechanic)
I will reinstall also SafeRobot software too.
And will check better everything from start.

KR16_2 you have right, safety mode not possible doesn't affect drives on status.
SafeOperation are disabled yes , in safety parameters in Global Settings monitoring of parameters are disabled, having setted true. I dont need all those monitoring.

The matter is how to unblock status drive from On to Off, drives contactor may be blocked, deffect..?

Meanwhile I replaced KPS 600 and safety board CI3-tech, no change I drives status on , meaning green. Is not their fault therefore.
Tomorrow I will replace also RDW .
MFC-DSE seems ok , service diagnosis do not indicate any error, everything looks normal.
Anyway I unplugged MFC board connections and plugged back, no change in I status.

I cannot understand what else still generate this blockage with drives on. Frustrating matter.

When disconect the bus cable from PC to KPS 600 , there is no change on teachpendant monitor, no error, no missconnection indicated, ....and status drive remain on ( green).
Could that indicate a problem with MFC-DSE card?
I have three cards in PC slots, one is MFC-DSE, second is VGA card for monitor and there is a third one where from leave bus cable to KPS 600
This is in slot 1 and I think it is an optional Interbus card for Ethernet.
It could be the fault of this Interbus card too?

This sounds right,.....meaning what? Can you better explain?
