Main Rack and Expansion Racks
You can add Units and Optional Modules to a Rack to expand functionality. However, if a
restriction such as the power supply capacity or number of Base Unit slots for one Rack is
exceeded, you must add an Expansion Rack.
You can achieve the following things by adding Units or Optional Modules to a Rack.
•
Increase the number of Optional Modules that you can use.
•
Increase the number of axes that are controlled.
If you add Racks, the Racks are classified into the Main Rack and Expansion Racks.
Refer to the following section for an expansion example.
