Millennium Series Motion Controllers for Stepper Motors for ISA-bus

Model 3m-0x-S
The Millennium stepper motor multi-axis motion controllers model 3m-0x-S implement the Navigator MC25xx series chipsets - dedicated motion processors from PMD. These controllers harness the power of the Navigator high-speed DSP chip and incorporate ASIC and surface mount technologies. They can install directly into a PC AT slot (ISA bus compatible) or can work standalone communicating via a serial link. The Millennium controllers are available in configurations of 1, 2 or 4 axes.

The DSP unit provides S-curve, trapezoidal, velocity contouring and electronic gearing profiling modes for Pulse and Direction signal output. Onboard memory allows designers to capture on-the-fly motion data for analyzing system performance and diagnostic purposes. Motion trajectory segments can be blended into continuous motion path in the velocity mode.

The boards interface to external components via a 100 pin high density connector providing motor outputs and reading pulsed encoder (incremental or absolute) for on-the-fly motor stall detection, limit switches and home indicator input signals. They are capable of handling eight analog inputs and eight user-defined discrete I/Os.

The cards are supported by C-MotionPlus™ and CyberMotion™ - extensive C-language software libraries and Windows and Linux drivers, which allow development of any motion'control application. EasyMotion™, a GUI application package with the industry's first ever MotionWizard, assists in a quick and easy way to set up and tune even complex electro-mechanical systems.

The boards can be used in a variety of industries, such as robotic, machine tool, semiconductor, medical, food processing, textile and many others.
