Automatic Operation (Synchronous Control)
12-4
12.2 Settings for Master and Slave Axes
12.2.1 Selection for Master and Slave Axes
The master axis serves as a reference for synchronization control. Start and stop requests for
various operations are made to the master axis under synchronous control. It is possible to
select one of the following master axes.
Types of master axes
Types of
master axes
Outline
Existing axis
Axis that can be physically controlled by the control unit (1~8 axis).
It is used when you hope that the master axis is also used as a control object.
When an actual axis is used as the master axis, it is allowed to use axes other than the master
axis (7 axes) as the slave axes.
Virtual axis
A virtual axis exists in the control unit.
The virtual axis does not perform the motor control
Pulse input
The action to make the pulse input value of the input unit as the master axis.
It is used when connecting external devices on the bases of synchronous control such as
external encoder.
When pulse input is used as the master axis, the slave axis operates according to the pulse
input. Therefore, special attention must be paid when stating or stopping operations via the
control unit.
