Resolving Multiple Topology Errors


This week we have been looking at multiple topology errors on a Dugard Eco VMC with Siemens 828D control and Sinamics drives.

After confirming that all the hardware was OK, we discovered that the control had lost the topology data for drive object 6, which was the 4th axis and all of it's associated hardware (motor, drive, encoder and SMI module).

Using HMI startup and our Simatic field PG, we were able to reteach the control and configure the 4th axis. We made new backups and got the machine back up and running again.

At Control CNC Services Ltd., we offer a cost-effective CNC machine prevention maintenance service to help keep your business up and running.

Please contact Control CNC using the green button at the top of this page if you think we would be able to help with your machine. We cover the whole of the UK and Ireland. We can help you book a service, quote you for a repair, or help you purchase the best quality parts for your business.

This week we have been working on a spindle removal and refurb on a 30 year old machine.

We found this to be particularly challenging, as we had never seen one of these machines before and we were following the failed attempts of another machine tool repair company.
