Advanced Readout Functions
These advanced functions are only available on
General
Purpose and 950 Series Readouts with the Auxiliary keypad
pictured here.
Absolute / Incremental
The Readout has two measurement indexes. One is called
ABS (absolute) and the other INC (incremental).
The ABS measurement setting is designed to allow a user to set an origin point
on the Readout referenced to a fixed or known position. The INC measurement
setting is designed to take relative or incremental measurements from one point
to another. The settings operate independently allowing separate position
offsets to be programmed for ABS and INC. The origin, or known position of the
measuring system is not lost when using the INC measurement mode and is
recalled and displayed when the Readout is returned to ABS mode.
NOTE: The terms
“
Absolute
” and “
Incremental
”
are used here to describe a
measurement function or technique and should not be confused with Absolute
and Incremental when used in reference to the type of
Measuring Technology
employed by different ProScale products.
Absolute (ABS)
The Readout automatically enters ABS mode when power is first
applied. This is indicated by
ABS in the upper left corner of the
LCD. While in ABS mode, all position measurements are related
to the current system reference point.
To enter INC (Incremental) mode:
Press and Hold the
ABS
/
INC
key for 3 seconds.
NOTE: To change the timing of this key to Momentarily , see
Programming Parameter (Pr22).
Incremental (INC)
While in the INC mode,
INC is shown in the upper left corner
of the LCD. When INC mode is initially entered, the displayed position will
change to reflect a new reference point at the current position of the Encoder.
This is typically a position of zero (
0.00 ) but may be changed by using the
+
or
–
Key to enter an offset. Moving the Encoder in either direction will display the
distance moved from the initial INC starting point (plus any offset). To complete
another incremental measurement from the new position,
Momentarily press
the
ABS
/
INC
key. The Readout will again change to zero (or the previously
programmed offset). To return to the ABS mode, Press and Hold the
ABS
/
INC
key for 3 seconds.
