ENC_ACOR_PosStart
Definition of correction range: The range is
defined by parameters
P 0591 ENC_ACOR_
PosStart
Start position and
P 0592 ENC_ACOR_PosEnd
end position.
The start position is user-specified; the end
position is determined on the device side from
the maximum value of correction table
interpolation points used and the interpolation
point pitch.

ENC_ACOR_PosDelta
Interpolation point pitch: The positions at which
the correction interpolation points are plotted are
defined via parameters
P 0593 ENC_ACOR_
PosDelta
Interpolation point pitch and
P 0591
ENC_ACOR_PosStart
Start position. Between
the correction interpolation points, the
correction values are calculated by cubic spline
interpolation.

0-250 ENC_ACOR_VnegTab
Values of the correction table for negative
direction of rotation in user units.
596
0-250 ENC_ACOR_VposTab
Values of the correction table for positive
direction of rotation in user units.
