Standard Functions
The DP1200 can store up to 200 SDM (Sub-Datum) positions, or machining steps, into the memory.
Using SDM allows the operator to work to zero by calling up stored dimensions, instead of "working
up" to drawing dimensions. This eliminates the need to constantly refer to the drawing and reduces the
possibility of scrapping parts due to misread dimensions. It also speeds up positioning as the operator
is working to zero.
The SDM’s are stored as co-ordinates relative to the absolute datum position. If the absolute datum
position changes, the SDMs will "shift" to the new datum.
Once a repetitive sequence of co-ordinates is entered into SDM, the co-ordinates can be recalled at
any time.The positions remain in memory until altered by the operator. Simply assign any SDM num-
ber 1 - 200 to each machining step. When machining, call up each step (SDM) number and work to
zero. Sub Datums can be used for any or all axes. There are two ways to store Sub Datums; Teach
Mode and Program Mode.
