14.7
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.
Syntax
QECLRNON
QECLRNOF
Activate learning operation: QECLRNON
The actual learning operation is activated in the NC program using the command
specifying the axes:
QECLRNON (X1, Y1, Z1, Q)
The characteristics are only changed if the command is active.
Deactivating learning: QECLRNOF
After the learning motions of the required axes have been completed, the learning process is
simultaneously deactivated for all axes using
680
.
