3.3.3.2. Axis Type: Reference
A reference axis is an axis that has only an input, such as position, pressure, or force. A
reference axis does not have a Control Output and cannot control anything. A reference axis is
commonly called a "half-axis".
Reference axes are typically used for monitoring some quantity, such as:
• Position
• Velocity
• Acceleration
• Pressure
• Force
Creating a Reference Axis
To create a Reference axis, you must add a new reference axis or change an existing
axis. For details on defining axes, see the following topics:

Using Reference Axes
Reference axes are typically used for monitoring some quantity. The following are
examples of specific uses with the RMC:
• Gear some axis to the reference input.
• Use the value of the reference to affect the flow of the User Program.
• Use the value of the reference in a Expression command in the User Program to
perform mathematical calculations.
3.3.3.3. Axis Type: Cascading Outer Loop
A Cascading Outer Loop axis is used as the outer loop of cascaded axes. A cascading outer
loop axis is identical to a control axis, but it provides a virtual Control Output, and does not
use a physical Control Output. This is only for advanced applications. For details, see the
Cascade Control and control axis topics.
For descriptions of all available RMC axis types, see the Axis Types Overview topic.
There are two types of cascading outer loop axes:
1. One-Input Control Axis
A control axis that controls a single quantity, such as position or pressure, is called a one-
input control axis.
