This was a first for us having never worked on one of these machines before. This is the XYZ UMC 5-X (The Challenger) - 5 axis VMC with Siemens 840Dsl control and Sinamics drives.
This particular machine is just over a year old and just out of manufacturer warranty. It had been suffering from multiple drive and profinet errors.
This included 380001 profibus / profinet startup errors, 150202 waiting for connection to PLC / NCK and 2001 PLC has not started up.
When we attended the site, we found a bad connection on a SMC module, a corrupt NC and completely flat PLC. After carrying out a full system clear out and reload of NC, PLC and Drives, the machine came back to life. We monitored it for several hours and gave it a clean bill of health.
