13.4 13.4 Learn compensation characteristics (QECLRNON, QECLRNOF)
Function
Quadrant error compensation (QEC) reduces contour errors that occur on reversal of the
traversing direction due to mechanical non-linearities (e.g. friction, backlash) or torsion. On
the basis of a neural network, the optimum compensation data can be adapted by the control
during a learning phase in order to determine the compensation characteristics
automatically. Learning can take place simultaneously for up to four axes.

Programming
QECLRNON
or
QECLRNOF
Activate the learning process: QECLRNON
The actual learning process is activated in the NC program with the command QECLRNON
and specification of the axes:
QECLRNON (X1, Y1, Z1, Q)
Only if this command is active are the quadrants changed.
Deactivate the learning process: QECLRNOF
When the learning movements for the desired axes are complete, the learning process is
deactivated simultaneously for all axes with QECLRNOF.
