6.1.1.2. Segmented Error Correction (SComp):
Segmented Linear Error Compensation (SLEC) is used when the results of the
comparison with a reference standard shows non-linear error. In SLEC the entire
axis travel is divided into user defined segments. The error in each segment is
compensated with a single correction factor. Each correction point is measured with
respect to the starting point. This starting point is usually set close to the end of the
scale. This starting point can coincide with the absolute datum point or machine
reference. (Refer section 6.2 for machine reference.)
The standard procedure is to divide the entire axis travel in necessary number of
segments and encoder travel for each segment is recorded along with the reference
standard measurement. A table is prepared where reference standard measurement
and encoder reading for same travel are maintained. This table will be used to feed
SLEC data in DRO. EL250 can accept maximum 25 nos. of segments for each linear
axis.
i. Enter SLEC menu, by referring 6.1.1.
ii. For segment no. 1, keep values of Disp value and Slip Value as 0.000
only. Enter the slip (standard) values and the display values for
segment no.2 and onwards using numeric keys. Use
and
key to move cursor between display and slip value.Press
key to save these values.
iii. Use
or
key to go to next or previous segment
respectively.
iv. When data for all segments is entered into SLEC menu, press
key to save them.
