2. The slave axis will start trailing operation when the marker sensor sig-
nal is input. The trailing operation will be completed once the slave axis
synchronizes with the position of the master axis (Marker sensor ON
position + catch-up position offset).
3. The slave axis is operated synchronizing with the master axis in the ra-
tio of 1 to 1.
• Catch-up position offset is specified as the distance from Marker sensor
ON position on the coordinate system of the slave axis.
• Marker sensor ON position is specified as the position on the coordinate
system of the slave axis.
• If the speed in synchronization exceeds the speed specified in the param-
eter [P2AA01: Maximum rapid feed rate], the alarm [3011h: Synchroniz-
ing slave axis excessive speed] will occur.
• Master axis classification determines whether to synchronize the slave
axis with the master axis command value or feedback value.

• SYNC command execution will be completed when the trailing operation
is completed and the synchronization is established.
• During the command execution, the command code "0018h" is output to
the system variable "Command execution status" (SW0228 for Axis 1).
(For details of command codes, see 4-5 System Variables Command
Code in Command Execution Status on page 142.)
