代码 650: RP-Pallet Not Engaging RP Main Drawbar

This alarm occurs when the Pull Stud cannot properly engage the Ball Pull Collet. If this happens, the Ball Pull Collet has been pushed down into the Collet Housing and pallet clamping is not possible. Check alignment of the pallet changer's frame with the adjustable Hard Stops. Check the Pallet Pull Studs and the RPMain Drawbar Ball Collet for damage or obstruction. Remove any debris that may have entered the Collet. Check that the six balls in the collet float within the holes. Consult the operations manual. If lift to the H-frame has been lost following a collet jammed condition, orientation of the pallet is not guarantied. Check orientation of the pallet as well. Zeroing of the A Axis is not safe if lift has been lost. It may be necessary to remove workpiece from the pallet. After correcting the condition, run an M50 to continue machining.
