8.1 Synchronous Control
8.1.1 Outline of Synchronous Control
 Synchronous control
The positioning unit in synchronous control operates a master axis so that salve axis will
operate in synchronization with the master axis. The use of synchronous control provides the
following merits.
1. Ease of setting
A number of related axes can be operated with ease by designing the operation of the axes
based on the master axis.
2. Ensuring operational safety
If an axis comes to a stop for some reason while the positioning unit is in synchronous control,
all the relevant axes under synchronous control will come to a stop. Therefore, you can easily
increase the safety of the positioning unit.
 Outline of Synchronous Control
The synchronous control provides the following functions. These functions are executed in
order, and the slave axes operate according to the operation result of each function.
Functions Outline
Electronic
gear
The number of pulses multiplied by the preset electronic gear ratio is output according to the
operation of the master axis.
Electronic
clutch
The operation of the salve axes can be separated from the operation of the master axis by
disengaging the clutch. (The slave axes do not operate.)
Electronic
cam
A function to output pulses according to the preset cam pattern.
Calculates the operation phase of the master axis and outputs cam pulses according to the phase.
The cam pattern is set with a setting tool.
 Execution Order of Synchronous Control and Setting Procedures
The following section provides information on the outline of functions achieved by
synchronous control and setting procedures for the functions.

Make master axis settings for each operating axis.
Each operating axis will work as a slave axis if master axis settings
are made for the operating axis.
Select the use or non-use of the electronic gear. Various electronic
gear settings are required if the electronic gear is used.
Select the use or non-use of the electronic clutch. Various
electronic cutch settings are required if the electronic gear is used.
Select the use or non-use of the electronic cam. Various electronic
cam settings are required if the electronic gear is used.
In addition, electronic cam pattern settings are required in the case
of using the electronic cam.
