Diameter axes
Select DIAMETER AXES to set the axis values to either diameter or
radius values depending on the requirements of the drawing. .
Cursor to DIAMETER AXES and press ENT.
The cursor will be in the X axis field. (The field will default to
RADIUS). Depending on the parameter you need for that axis either
press the DIAMETER soft key or press ENT to leave as RADIUS and
advance to the next axis field.
Press USE, then USE NEW SETTINGS.
Radius/Diameter Display
POSITIP 880 can display either the radius or the diameter for you.
When the diameter is being displayed, the diameter symbol (Ø) is
shown next to the position value.
Edge finder (milling only)
The diameter and length offset of the edge finder are set in this form.
Both values are in the units indicated in the form.
The numeric keys are used to enter values of diameter and length. The
diameter must be greater than zero. The length is a sign value
(negative or positive).
Soft keys are used to select the units for the edge finder dimensions.
The entered diameter and length values are not converted when the
units are toggled.
The edge finder values will be retained on a power cycle.
Measured value output
With the measured value output feature, the current axis display
positions and probe measurement values can be sent over the serial
and /or parallel ports. Output of the current display positions is
activated via an external hardware signal (requires optional Auxiliary
Machine Interface) or via a command (Ctrl B) sent to POSITIP 880 over
the serial port.
The Measured Value Output form is used to set data output during
probing operations to On or Off. It is also used to set the display freeze
option.
Data Output Probing - This may be set to either On or Off. When On,
the measurement data is output when the probe operation is
completed.
Display Freeze - Set to either:
Off - The display is not stopped during measured value output.
Concurrent - The display is stopped during measured value output
and remains stopped while the switching input is active.
Freeze - The display is stopped, but is updated by every measured
value output.
Refer to chapter II-5 Measured Value Output for information on the
format of the output data.
