Master Offset

If the material and welding point are not initially aligned, as shown, the master offset must be applied to consider the position difference.

Without the master offset, the master device position is already inside the first interval as soon as the first material passes the welding point.

The following figure shows that the master cycle intervals are offset by 50 counts. The master interval is shifted from 0, 2,000, 4,000, and 6,000 to 50, 2,050, 4,050, and 6,050.

The following figure shows the camming profile used for the application portrayed in the previous figures.
