Haas CNC Alarm 180 (Mill) PALLET/FIXTURE NOT CLAMPED
Alarm Description, Cause & Remedy
Pallet/Fixture clamped input indicates pallet or fixture is not clamped and it is unsafe to run the spindle, jog an axis, or start a part program by pressing Cycle Start. It could also mean that a previous pallet change was incomplete and the pallet changer needs to be recovered. EC-300: Make sure there is no debris obstructing pallet clamp assy. The pallet clamp switch assembly may need servicing. The switch assembly is located under the pallet, behind the clamp plate. EC-400/500: The machine gets this alarm at beginning of a program if there is no pallet on the receiver. Check for debris between pallet and receiver. Check air pressure. Test switches at rotary union located under receiver. VFAPC: Alarm occurs when the spindle is commanded, but the pallet is unclamped. E-Stop may have been pressed during a pallet change. Run an M50 to reset the pallet changer. Pallet clamp switch may need servicing.
