We are having this same issue with a CNC 5-axis machine from DMG-Mori. When the machine was last powered on, everything was fine and it went through a normal shutdown sequence. This morning when we turned the machine on, all the NCU leds illuminate steady ORANGE, and the 7-segment LED flashes 3 3 4 6. in that order. Turning power off and back on has no effect. The control screen has a message on it that says "Warning : Connection established - no DHCP server available" and is hung in the Thin Client Boot Loader stage where an IP Address is obtained. There is a Bihl/Wiedemann profibus controller that displays "Profibus error - no connection". The PDF attached to the reply to this post doesn't really state what the 3346 means.. it seems to be that the NCU is not responding properly, but what the troubleshooting steps are is not clear. Any suggestions would be greatly appreciated. ------------------------------------------------------------------------------------------ |

Hellowoyansky, LED Orange illumination is indication BIOS boot is under progress. 7 segment display 3346 reppeatedly indicates, - host name is set, system logging is started, & server connection establishment is started. It looks like PCU50.3 & TCU connection coul not be established. Please check the connection between NCU, PCU 50 & TCU. BTW, is it via Profibus or via Ethernet. HTH. |
