The C-842 PC plug-in DC motor controller board is the optimal solution for applications where a multi-axis precision positioner is to be computer controlled by a PC. Integrated low noise, linear amplifiers allow operation of micropositioning systems with motor/gearhead drives without additional external amplifiers, reducing costs and simplifying the set-up.

The C-842 employs a fast DSP (Digital Signal Processor) providing high performance PID motion control with many options of trajectory generation and filter setting. Position, velocity, acceleration and several other motion parameters can be programmed individually for each axis on-the-fly. The C-842 can be installed in 16-bit ISA PC slots.

Any quadrature TTL incremental encoder can be used for position feedback (linear scales and rotary encoders, interferometers). Eight TTL inputs and eight TTL outputs are available for flexible automation (trigger functions etc.).

The C-842 offers full access to the internal processor functions via the I/O address space. Programmers can use hex commands and 32 bit parameters for very fast communication (3000 data/sec). The motor controller also comes with a variety of software tools such as LabViewä drivers, libraries in C, PASCAL and BASIC and a DOS program for instant, easy operation without low-level programming. Windowsä programming is supported by 32 bit and 16 bit DLLs (click here for further information on C-842 software tools).
