The PCI321 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.

Features
> Controls two 2-phase or one 4-phase motor(s)
> Firmware compatible with PCI321 intelligent stepper motor controller for external amplifiers
> Interrupts on position breakpoint, trajectory complete and command complete
> Each phase delivers 3A@55V and is over-current and thermal protected
> Programmable hold-current reduction
> User configurable maximum current
> Brake support
> Full-, half- and micro-stepping (up to 16 micro steps per full-step)
> Two home sensor inputs
> Step-rates up to 50kHz
> Programmable acceleration from 50Hz/sec to 5,000kHz/sec.
> Hardware synchronization lines
> PCI9050 Controller by PLX (PCI 2.1compliant)
