I'm using okk's pcv-510 machining center.

There is a problem with tool change.

While in M16 commend, spindle can't find the location and spinning countinously. With an error message 2026 oreint moving is not good.

This proble is not in every situation. It occurred when machine using over some hour.

I try to do something. Already change magnetic sensor and plc plate. but still not good working.

Is there anyone can help? I also need a pcv-510's manuals too.

thanks.
