1.12.3 Configuration Examples of Controlled Axes
- Gear grinder
Spindle : EGB master axis serving as a tool axis
First axis : X
Second axis : Y
Third axis : C axis (EGB slave axis serving as a workpiece axis)
Fourth axis : C axis (EGB dummy axis, which cannot be used as a
usual controlled axis)
Fifth axis : V axis (EGB slave axis serving as a dressing axis)
Sixth axis : V axis (EGB dummy axis, which cannot be used as a
usual controlled axis)

NOTE
A sampling period of 1 ms is applied when feedback
pulses are read from the master axis; the
synchronization pulses for a slave axis are calculated
according to synchronization coefficient K; and the
pulses are specified for position control of the slave
axis.
