How many coordinate systems exist, and how many can the Active Coordinate System access?

• A. Five coordinate systems exist, and the Active Coordinate System can access four of them
• B. Four coordinate systems exist, all accessible
• C. Six coordinate systems exist, four accessible
• D. Three coordinate systems exist, two accessible

Answer: (A)

In Motoman programming, you work with multiple reference frames called coordinate systems, and the Active Coordinate System is the frame that motion commands are interpreted in. There are five coordinate systems defined on the controller, giving you options to target positions from different perspectives (such as world/base, tool, and user-defined frames). The Active Coordinate System can access four of these five, with one reserved for an internal reference or not available in normal operation. That’s why the correct statement is that five coordinate systems exist and the Active Coordinate System can access four of them. If you need to know exactly which frames are available on your model, check the controller’s ACS menu or its documentation.
