The VME321 Intelligent Stepper Motor Controller with Amplifiers is an ideal solution for all applications where stepper motors must be controlled with a maximum of flexibility and a minimum of overhead. The local processor handles all high-level commands to provide maximum control for both straightforward as very complex applications.
This VMEbus board has a 6U form and is also available as 3U VMEbus board.
