9.11 INTERPOLATION TYPE STRAIGHTNESS
COMPENSATION
The following two functions are available:
<1> Straightness compensation 128 points
<2> Interpolation type straightness compensation
9.11.1 Straightness Compensation 128 Points
In conventional straightness compensation, compensation data is set
for four compensation points with parameters to obtain compensation
data along an approximate straight line connecting the four points and
perform compensation based on the data.
This function allows data for up to 128 equally spaced compensation
points to be set in the same way as for ordinary pitch error
compensation.
By this function, fine compensation is also available for ”straightness
compensation.”
This function also allows up to six combinations of movement and
compensation axes for straightness compensation.
9.11.2 Interpolation Type Straightness Compensation
In conventional straightness compensation, for each interval between
pitch error compensation points set by parameters, the amount of all
straightness compensation at the compensation point is output and
compensation is performed.
This function equally divides the amount of compensation for each
interval between pitch error compensation points for compensation
data set using 128 straightness compensation points and outputs it as a
compensation pulse.
NOTE
To add the interpolation type straightness
compensation option, the stored pitch error
compensation option is also required.
