3-1-7. Learning Function
When positioning is completed, the Learning function checks the discrepancy between the target stop position
and the actual stop position. It then automatically adjusts the STOP zone for the next operation based on the
discrepancy.
Depending on the positioning direction, either the FORWARD or REVERSE stop zone will be adjusted.
(The STOP zone is not corrected for “START from STOP zone” positioning operations.)
Stop zone corrections are performed when the “positioning completed” signal output occurs (“positioning” signal is off).
Machines with large inertias can be accommodated by changing the “positioning completed” detection timer
(parameter No.51).
If the stop position following a positioning operation is not within the In-Position zone, positioning will be repeated
maximum two times (RETRY operation) based on the STOP zone adjustment made by the Leaning function.
Note
The Learning function is not always effective for all positioning applications.
