.............................
G90 G00 U1000.0 V200.0 B0 ; Move to the dressing start point.
M56 ; Start B-U synchronization.
Mxx ; Rotate the hob axis.
G04 X1000 ; Wait until the rotation speed of the
hob axis becomes constant.
G01 V100.0 ; V-axis approach
G01 U200.0 ; Dressing
G00 V200.0 ; V-axis escape
M57 ; Stop B-U synchronization
Caution
1) A reset does not cancel synchronization.
2) Synchronization is achieved even if the slave axis is in any of the
following states:
♦ Interlock
♦ Feed hold
3) Synchronization is not maintained if the slave axis is in any of the
following states:
♦ Machine lock
♦ Servo off
4) The master axis cannot be a chopping axis, angular axis control axis,
mixture control axis, or Superimposed Control axis.
The slave axis cannot be a chopping axis, a PMC axis, angular axis
control axis, Synchronous/mixture control axis, or Superimposed
Control axis

- Page 2General 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, su

Moreover, a synchronous group which makes the PMC axis a master axis must turn off the synchronous mode at the end. 15) When a synchronous group which makes the axis a master axis is used, a syn

In this case, if an automatic reference position return to origin is done after the synchronous mode is canceled, the alarm of DS0405(ZERO RETURN END NOT ON REF) is issued.
