Preparations before making the initial setting (1/3)
By confirming the conditions of use in advance, the setting operation can be performed easily.
Let's start with the basic settings.
Items Indication Description Setting
Axis label Select the axis label to be used for the counter display
and RS232C command. The functions that can be
used differ depending on the selected axis label.
ABC display: Function for gauge type measuring unit
XYZ display: Functions for scale type measuring unit
Axis label:
ABC or XYZ
Master calibration When the power is turned on, the system automatically
waits for the reference point detection and
automatically reproduces the reference position of the
master block.
It is necessary to adjust the reference position of the
master block once before the power is turned on.
OFF: Useless
ON: Effective:
Input axis Select how to display the number of scale axes to be
connected. When you select "Additive Display", select
the polarity (+/-) of each axis as well.

Measuring unit
resolution
Set the resolution output from the measurement unit to
be used for each axis. The resolutions that can be
selected are length and angle. Expanded selections
increase the number of options.
*Angular resolution (1sec to 1 degree) when using a
rotary scale
Length: 0.05 to 100μm
*See Tables 1,2 and 3
or
Angle: 1 second to 1 degree
