Segmented linear error correction (SLEC)

SLEC compensates for machine irregularities and encoder non-linearities by
applying correction values to individual segments that cover the entire range of
motion along an axis. A maximum of 300 points (299 segments) may be used.
To apply SLEC to a measurement axis:
Verify that the appropriate encoder reference marks are selected in the
Encoders menu
Further information:
Cycle the power off and then back on to establish the machine zero if necessary
Reference marks or a manual reference position must be recognized
upon startup to create a repeatable machine zero. Machine zero is
required for SLEC error correction.
Highlight the Scale Factor menu
Verify that the Active parameter is set to No
When scale factors are used, they must be applied after error
corrections.
Highlight the LEC menu
Verify that all Standard and Observed fields contain the value: 1.000 to
eliminate the possibility that a previous LEC correction will influence this SLEC
correction
Highlight the SLEC menu
SLEC correction cannot be configured while SLEC is enabled.
Verify that the Enabled parameter is set to Off
