Hello Forum: I am a Service Engineer with no formal training on AB PLC. I have a system that uses Ultra3000 servo drives to control motion of a Gantry platform for an X-Ray machine. The issue the system is presenting is that all 8 Servo Drives will only get to Phase 2 of its initialization process. I have downloaded the troubleshooting guide found on this forum and it says this: " The drive is configuring nodes for communication. Wait for phase 3 or take corrective action until you reach phase 3"   My problem is that it will never reach Phase 3 on the 7 segment display, all 8 servo drives will simultaneously go back to 0, then 1, 2 and back to 0 again.  I tried replacing some of the drives and some of the data cables going to the motors, but this seems to me that the problem is before the drives even recognize the motors because I can disconnect a motor completely and the E30 that typically comes after I disconnect the datacable will not be displayed on the drive where the motor was disconnected. Any help will be appreciated. Best regards
