ZERO
Move the machine to the zero position of the
standard against which the axis is being
compared and zero the axis with the zero key.
STANDARD
Move the machine a known distance as
determined by the
standard and enter that value.
(j) Set Error Compensation - Segmented Error Compensation
ERROR SET
SEL.AXIS
Select the axis to be compensated using the axis
keys.
The axis displays will show which axes have been
selected for segmented error compensation.
SET ZERO
The start point must be at one end of the section
that is to be error-corrected. Points must progress
in sequence, i.e. there must be no reversals in
direction.
Move the machine to the desired start point,
press [ENT]
GO TO 1
The current position relative to the new zero
point is displayed in the relevant axis. Move to
1st (nth) correction point (against a standard).
Press [ENT] to move on
A gauge block, standard bar or laser measurement should be
Xo
used as the standard against which the displayed movement is
compared
Yo
Zo
Select another axis for compensation or press [ENT] to end.

ent
The scale travel is broken down into as many as 99 user-defined
ent
segments, each with its own correction factor, measured against
a high-accuracy standard.The following parameters need to be
X
identified:
Y
Starting Point - zero
1
Z
error
0
Reference Point
Each Correction Point is measured with respect to the Starting
ent
Point - zero - which is usually set close to one end of the scale.
The Reference Point can be set anywhere along the scale, and
does not need to coincide with either the absolute datum or
any of the correction points. However, it may be convenient to
make the absolute datum and the reference point the same.
Always approach the Starting Point, Correction Points and
Reference Point from the same direction. If you do not, then
the size of the tool or probe will render the measurement
inaccurate.
