Haas Alarm: 633 (M) APC-CLAMP ERROR – The pallet did not clamp in the amount of time allowed by Parameter 316. This alarm is most likely caused by the mill table not being in the correct position. This can be adjusted using the setting for the X position (#121, #125) as described in the ‘Installation’ section. If the pallet is in the correct position but not clamped, push the pallet against the hard stop and run M18. If the pallet is clamped, but not correctly, run M17 to unclamp, push the pallet to the correct position, and run M18 to clamp the pallet. Less common causes could be that the slip clutch is slipping, the motor is at fault, or an airline is blocked or kinked. After correcting the condition, run M50 to continue machining.
