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
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.
Existing axis
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.
A virtual axis exists in the control unit.
Virtual axis
The virtual axis does not perform the motor control
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.
Pulse input
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.
