I keep get Error code 11 when on Idle

[cc1433]

Hi, This is the problem,
As soon as I switch the machine on and I went through the CP-Tronic console and to the
DYN t=0 Test-1 and under that I get the following error
SBM- 1/2 7EFF

I went through all the other tests and there was no error's atleast nothing else was blinking. With this error I am allowed to run the machine and do all the other functions. After a few minutes of the machine on idle ( where the machine is on, and no motors are turning) the following error pops up

DYN t=0 Test -1
SRK - 7FF0
SVT - 7EFF
SBM_1/2 - 7EFF

and most of the time error 11 is displayed on the controller, and on the CP-Tronic screen a T with a circular arrow as per attachment is displayed.
At this point I am forced to switch the machine off and power it up to get along with my work.

I have checked the current drawn I have more than enough available.

Check the Interface between SBM in slot SBM1 and SVT. may b it is deffective.
