9.4 Synchronous Control
This is the command that control the operation synchronizing with the main axis or operating of encoder.
9.4.1 Speed Synchronous Control
This is the command that synchronize with sub axis in speed and control operation depending on speed
synchronous rate already set when main axis starts.
(1) Characteristic of Control
(a) Start and Stop is repeated depending on operating of main axis after execution of speed synchronous
command. The operating direction of sub axis and the main’s are same.
(b) If execute speed sync. command, it will be the state of operating and remain in the state of speed sync.
operation before release of speed sync. command.
(c) Auxiliary data of speed sync. command
The auxiliary data used in speed sync. command is as follows.
Item Setting value Description
Main Axis 0 (X-axis), 1(Y-axis), 2(encoder) Set the main axis of speed sync.
Ratio of Main
