Stepper Motor Controller for VMEbus – VME321

]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.


Controls four sets of two 2-phase or one 4-phase motors
Firmware compatible with VME322 intelligent stepper motor controller for external amplifiers
Interrupts on position breakpoint, trajectory complete and command complete
Programmable hold-current reduction
User configurable maximum current
Brake Support
Full-, half- and micro-stepping (up to 16 micro steps per full-step)
Eight home sensor inputs
Step-rates up to 50kHz
Programmable acceleration from 50Hz/sec to 5,000kHz/sec.
Hardware synchronization lines
