We have an Arrow 1000 with Vickers drives. We have been experiencing intermittent fault which caused the machine to shutdown.

We get 44-52 C Axis Encoder Error, X Axis Encoder Error, Y Axis Encoder Error and Z Axis Encoder Error all in succession together..

The last time this happened we checked some connections, restarted the machine and were up and running for awhile.

I have a hunch that something is vibrating loose but have no way to pinpoint it. Any suggestions?
