1.6 Axis error compensation
The HEIDENHAIN contouring control can compensate for mechanical defects in the machine.
The following axis error compensation is possible:
– linear axis error compensation,
– non-linear axis error compensation,
Either linear or non-linear axis error compensation can be activated.
1.6.1 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.
