5. Notice
The limitations of the synchronous operation are the same as the simple synchronous control.
It is recommended to specify the command for automatic return to the reference position (G28)
or second, third, fourth reference position return (G30) in the normal operation mode.
Keep the manual absolute switch on during the synchronous operation. If it is off, movement
along the slave axis may not be correctly controlled.
If the command for changing the mode to the independent operation is issued, it will not
change until the next two or three blocks including this command block. By specifying the M
code for changing the mode as a non-buffering M code, it will change the mode from the next
block. But in the case of changing to the synchronous operation mode, .
Set the number of the master axis to parameter No.8311 for setting of the master axes and the
slave axes. If the same numbers as the master axis were set to the parameters No.8311, the
axis of the smallest slave axis number would be available.
The combinations of the master axis and the slave axis are maximum 4 pairs. If over 4 pairs
were specified, the pairs of the 4 smallest slave axis number would be available.
If the parameters No.8301#0,l(SYO,SYl) are set for the synchronous control, the twin table
control can not be used. The simple synchronous control is only available in this case.
Inthe independent operation mode of slave axes, if the command to specify the origin of the
workpiece coordinate system(G92) or of the local coordinate system(G52)
