5.1.1 Using Incremental
When the DP8 is set to incremental mode, it can be
used to display each new position relative to the last position.
This is also known as point-to-point use.
On setting to incremental you can reset each axis by
pressing [ Xo ] [ Yo ] or [ Zo ].
As an alternative to resetting the axes, you can enter the coordinates relative to the current incremental
position. If done in a negative sense, the operator can move to “0.000” which may save a great deal of
machining time.
Each time you switch to incremental mode, the DP8 will display the position relative to the last reset
position while in the incremental mode.
5.1.2 Using Absolute
When the DP8 is set to absolute mode it will display the
position relative to an established datum point.
5.1.3 Establishing the Datum
When you reset the display in absolute mode, you are setting the current position of your machine as your
datum point. All absolute positions will be measured relative to this datum.
To set the datum, position the machine at the point you intend to establish the datum and then reset any or
all axes, while in the absolute mode.
The diagram below is used in the following example to show Absolute and Incremental modes.
