b ) c ) and d have the values 1 ) 3 ) 6 0 j and 1 2 6
respectively.
In stored pitch error compensation, the amount of compensation is set individually
for each compensation point. In inclination compensation, however, the amount of
compensation is calculated for each compensation point by setting the amount of
compensation for the four representative points.
[For instance, in the above drawing, the amount of compensation at each of the
compensation points between point a and b is given by (fl-err) / (b-a) I
3. Notes
( 1) The inclination compensation function becomes effective after the reference
point return on the compensation axis.
( 2 ) Be sure to turn off the power to the NC after setting the parameters for
inclination compensation.
( 3 > Set parameters according to the following conditions :
l The amount of compensation at a single compensation point must be
in the range between - 1 2 8 and 1 2 7.
l Set the compensation points so that a I b 5 c 6 do
l The compensation points must lie between the negative (-) end and
positive (t) end of the stored pitch error compensation points.
All four points can be set to 0, however, in this case no compensation
will be performed.
(4 ) The sto re pitch error compensation option is necessary to use the optional d
inclination compensation function. In this case, the number of compensation
points on each axis must be fewer than 128.
(5) This function can also be used on linear and rotating axes.
