Hi guys. Machine is an '07 VF-2ss. Main regulator is at 82psi and drops to 80 during tool changes. The small regulator directly behind the main is set at 20psi and drops to 18 during tool changes. Draw bar tension was just checked by my HFO at 1,080psi. Clean dry air. Shop is heated and cooled to between 65 and 75 degrees 24/7.
We've been getting alarm 130 - Tool Unclamped after tool changes, but randomly. Some days it won't alarm at all, other days it can alarm as often as 3 times during a 3:14 cycle with 7 tool changes. It does it at 100% and 50% rapids.
Here's the thing: When it alarms, the tool is absolutely clamped correctly, every time. All we've been doing is resetting and restarting the program with no attention to the tool in the spindle and it runs just fine.
What should I be looking at? Could this just be a very slightly slow moving switch that needs to be cleaned?
