Linear Axis-Error Compensation - HEIDENHAIN TNC 415 Technical Manual

1.6.3 Linear axis-error compensation

One linear axis-error can be compensated per axis. The axis-error is entered, with the correct sign, in
machine parameter MP720. The error is positive if the table travel is too long, and negative if the
travel is too short.
MP730 set the axis error compensation to linear or non-linear. Linear axis error compensation is not
active for rotary axes.
