FANUC Series 30i/31i-MODEL A
Flexible synchronization control
General
This function is provided for machines that require synchronizing two or
more different gear ratios, such as a hobbing machine.
The function can simultaneously place up to four sets in synchronization
independently. For example, it is possible to realize special hobbing
machine functions, such as synchronization between a hob axis and one
workpiece axis, Z-C synchronization in helical gear cutting, and Y-C
synchronization in hob axis shifting
The specification of flexible synchronization control is as follows:
1) Master and slave axis numbers, and gear ratios are set in parameters.
2) These parameters are divided into four groups. So, four
synchronization operations can be performed simultaneously
3) The same slave axis can be specified for more than one master axis.
4) Synchronization is started and canceled by DI signals received from the
PMC.
However, switching DI signals during an automatic operation requires
using M codes specified in parameters.
5) Two Cs axes can be used as master and slave axes.
