  • For NI Motion Contoller Series
  • Includes both power stage and idustrial connectivity for motion peripherals such as switches, encoders, etc...
  • Ease of cabling and easy of maintenance

Two types of modules currently available

DC Linear for low noise (no switching) DC motors up to ±3A / 60V

EC Brushless for EC motors with Hall sensors up to ±8A / 60V

National Instruments NI Motion controllers (73XX Series, PCI or PXI format) are longstanding yet powerful motion controllers that can be used for many applications. In certain circumstances, they may come as an alternative to solutions using NI SoftMotion on a Real-Time controller.

The NI Motion LabVIEW API driver is organized into high-level straightforward VIs for seamless simple application developpement, and advanced detailed VIs for high performance systems.

However, NI Motion controllers only offer low-level and low power signals, and interfacing them to a full industrial motion system (motors, encoders, limit switches) may be a tedious task, requiring the assembly of power amplifiers, differential line receivers for encoders, and opto-isolation / level shifting for limit switches.

We have developed DC and EC modules with the above components fully integrated :

These modules are designed to fit in a common chassis that routes all the needed lines from the 73xx controller 68 pin connector to 4 slots, one for each axis / module.

Connections are dispatched with a "1 sensor - 1 cable - 1 connector" philosophy, removing the need for all intermediate elements (like terminal junction blocks for power distribution), the sensors being directly wired to the chassis.

The chassis includes various power supplies. A small 5V supply powers the encoders and the internal electronics, while the main power for motors can come from one single or several separate supplies (routable to individual modules), allowing to drive motors with different voltages in the same chassis.
