2. Configuration
The start of Angle based Learning control are the usual way to synchronize the start of High-speed cutting
(G05) and the new way to synchronize the start of PMC signal.
It is necessary to refer to angle as a standard. You can select position feedback or position command as this
reference position. And you can select feedback or command of the other axis. In this case, it is necessary to
give feedback or command of reference axis to odd axis.
Refer to Fig.2-1 Angle based Learning control configuration diagram.
Fig.2-1 Angle based Learning control configuration diagram
2-1. Application examples
(1) Variable Spindle speed (G05)
In case of variable spindle speed with fitting linear axis amplitude, Angle based Learning control can be used.
Because linear axis refer to spindle command, you must give spindle command to the dummy axis.
