Subsequent learning
The learnt characteristics can be optimized with
subsequent learning. The data stored in the user
memory are used as the basis for optimization.
Optimization is performed by adapting the sample
NC programs to your needs.
The parameters of the learning cycle (e.g.
QECLRN.SPF) can also be changed for optimization
•
Set "Learn mode" = 1
•
Reduce "Number of learn passes" if required
•
Activate "Modular learning" if required and define
area limits.
Activate 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 learning process: QECLRNOF
When the learning movements for the desired axes
are complete, the learning process is deactivated
simultaneously for all axes with QECLRNOF.
