eusty SkyeFire Thank you for your reply~!
We didn't restore any archive,.actually we don't have ,the harddisk got problem and the old archive we did backup before is unavailable.we changed a new harddisk and do a standard system image.
The "MACHINE.DAT" which runs in the robot now is a standard one which copied from D:\....(Every kuka robot got a backup in disk D) So we cann't compare the old and the new.
The new controller is the same type with the old one, just 7 KSD in it~~
I think we have to check whether the new controller KSD modle match the old Axis1 properly for motor. We think they are the same ,but we didn't check that.
Thank you for your help again~!
