To specify that the input data is the actual reading, type “M” and
press the
[TRANSMIT]
key or just press the
[TRANSMIT]
key at the
prompt:
“MEASUREMENT(M)/DEVIATION(D)?”.

is being displayed. Press the
[PROC SELECT]
key to change the
active process. You can only access the axes in the currently
selected process.

To specify that the input data is the difference, type “D” and press the
[TRANSMIT]
key at the prompt. The message on row 5 of the Axis
Calibration screen, “MEASURE,” changes to “DEVIATION.”
The control prompts the user to select whether measurement starts at
the most negative or positive position on the axis. To start at the
most positive position on the axis, type “+” and press the
[TRANSMIT]
key at the prompt: “STARTS AT THE MOST +/--?” or
just press the
[TRANSMIT]
key. To start at the most negative position
on the axis, type “--” and press the
[TRANSMIT]
key at
the prompt.
Important: The input data type and the start measurement point are asked
only when there is no data for the axis. If the user wants to change either
of the two, all the data for the axis must be deleted by deleting all
measurement points with the
{DELETE POINT}
softkey.
Entering Axis Calibration Parameters
Use the following steps to enter the Axis Calibration data:
1.
Move the axis to the most negative position on the axis if this
position has been selected as the start point. Otherwise, move the
axis to the most positive position on that axis.
2.
Press the
{INSERT POINT}
softkey. The control reading appears on
row 7 in the ABSOLUTE column.
If the difference option has been selected, 0 is automatically
displayed in the DEVIATION column for the first point entered for
the axis.
If the difference was not selected, the value displayed for the control
reading (ABSOLUTE column) and the actual reading (MEASURE
column) are the same.
