Digital Servo Drive/Controllers

The COMPAX servo drive/controller family is the highpowered cousin to Compumotor's line of Gemini low- to midpower servo drive/controllers. Providing an ideal solution for motion control systems where 120VAC - 460VAC direct input power is used, the COMPAX family provides up to 35kW continuous/70kW peak drive power for those more demanding high-speed, high-inertia, high-load applications. The COMPAX family is flexible, offering the choice of either standalone or modular packages for single- or multi-axis needs, thereby providing a complete motion control solution in a highly reliable and integrated package.

All COMPAX units incorporate the easy-to-use Servo ManagerTM front-end software package – a user-friendly,parameter-based configurator that greatly simplifies setup and programming for software users of any level.

The COMPAX can communicate via ASCII and binary or via a number of supported fieldbus protocols for direct interface with PCs, HMIs and PLCs. Moreover, any standard COMPAX unit can be upgraded with specialized functionality and/or alternative feedback devices, allowing users to tailor the COMPAX to their specific application needs.

This combination of performance, flexibility and expandability makes the COMPAX a powerful and valuable member of the Compumotor servo product family.
