Axis Type Setting
Virtual Axis
*1. For a 2-axis PCU, the default value is [2] for axis 3 and axis 4.
Set the axis type. When Virtual Axis or unused axis is selected, I/O wiring is not necessary.
Axis type becomes enabled at power supply ON, restart, or setup.
If you select [1: Virtual Axis] under axis type setting, you can use the axis as a Virtual Axis. A
Virtual Axis does not have any actual input/output and is used only for calculation purposes. In
a similar manner as a Physical Axis that actually outputs pulses, a Virtual Axis changes its
present position or status only on the PCU based on the command for each axis operation.
A Virtual Axis is different from a Physical Axis in the points below:

The command present position is the only present position. The feedback present position value
is always the same as the command present position. An attempt to execute present position
