VME321

Stepper Motor Controller with Onboard Amplifiers VMEbus

The VME321 is a cost-sensitive stepper motor controller 6U VEMbus board with amplifiers. Its rugged design features are ideal for extreme environments, ensuring a long, reliable service life.

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 well as very complex applications.

This board has a 6U form and is also available as 3U VMEbus.
