5.1 Outline
When the operation of axis A and axis B is not synchronized, the frame of the machine may
twist as shown in the below figure, which can damage the machine or impact the quality of
products.
Position Deviation between Axes Overflow Detection detects twisting of the frame of the
machine. To do this, the allowable position deviation between both axes is set in advance, and
an alarm or warning is generated when the allowable position deviation is exceeded.
The position deviation between axes is the difference between the feedback position (APOS) of
axis A and the feedback position (APOS) of axis B.
