MOTENC-Lite: 4-Axis Motion Control & Data Acquisition PCI Board (pn 7541 and 7544)


The MOTENC-Lite PCI board is designed for PC based real-time systems controlling machines that require precision motion control. These include, CNC machines, Routers, Pick and Place machines, Robots and so on. The board has all the necessary components to implement a precision digital feed back control system. Analog outputs from the board drive the Motor Amplifiers using industry standard ±10V interface. The position feedback is generated by the quadrature encoder counters using 32-bit resolution. Utilizing the full 32-bit PCI bus, the board allows reading the 32-bit counter in just one read cycle. The Analog output settling time is just under 5 micro-sec and the CPU read-write cycle times are within 500 nano-sec. This allows the PID feedback loop update rate of 20KHz or more. The board has digital I/O to connect home, limit, and other switches and relays to implement a complete control system.

The MOTENC-Lite board is supported on EMC/EMC2 (Enhanced Machine Control) software. EMC is a software system for computer control of machine tools such as milling machines. More info available at

Product Highlights:
