Stepper Motor Controller for External Amplifiers VMEbus

The VME322 is a cost-sensitive stepper motor controller 6U VMEbus board to drive external amplifiers. Its rugged design features are ideal for extreme environments, ensuring a long, reliable service life.

Designed to drive up to eight external amplifiers, the VME322 is an ideal solution for all applications where stepper motors must be controlled with maximum flexibility and minimum overheads. Local processors handle all high-level commands to provide maximum control for both straightforward and very complex applications.

The VME322 is also available in 3U form factor and as a M-Module, PCI and CompactPCI.(3U and 6U) product.
