Looking at a Hardinge 710 Mill with 828D and Sinamics drives today with multiple X axis alarms. After a few tests a faulty motor was diagnosed, more specifically the SMI 20 unit on it had failed breaking motor encoder comms to drive.
We removed the motor and a new SMI 20 was fitted and config reloaded. The X axis was then a mile out as it had absolute encoder on so after a re-teach of absolute 0 position the machine was put back into production.
Another happy customer! If you are having similar issues with your machines please contact us for further details using the green "Request Booking" at the top of the page.
