Automatic Operation (Synchronous Control)
12.1 Synchronous Control
12.1.1 Outline of Synchronous Control
The positioning unit in synchronous control operates a master axis so that slave axes 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.
Function
The number of pulses multiplied by the preset electronic gear ratio is output according to the
Electronic gear
operation of the master axis.
Electronic
The operation of the slave axes can be separated from the operation of the master axis by
clutch
disengaging the clutch.
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
Electronic cam
phase.
The cam pattern is set with a setting tool.
