Example:

Y = F(Z)
Measurement length on Z axis = 1 000 mm
Desired distance between correction points = 1 000 mm : 64 = 15.62 mm

Possible exponent (base 2) = 2

The errors which have thus been determined can be entered in the form of a table directly into the
HEIDENHAIN contouring control. However, the axis-error compensation is only effective when it is
enabled for a specific axis by the machine parameter MP730.

Before entering the correction table the code number 105 296 must be entered. After the code
number has been entered the control will initially show the correction table for the X axis:

X = F(X)
