In addition to innovative system architecture and digital communication options, these drives come in a variety of designs and cooling types, delivering performance from 0.16 to 6,000 HP, and feature efficient engineering and quick commissioning resulting from innovative tools and simple wiring.

Functions for Increased Efficiency



  • Basis functions: Speed and torque control, positioning functions
  • Intelligent starting functions for automatic restart after a power interruption
  • BICO technology with interconnection to drive-related I/Os
  • Graphic configuring with free blocks using DCC to adapt the drive system in a user-friendly fashion to the machine environment
  • Integrated safety functions to cost effectively implement safety concepts

Controlled in feed / regenerative feedback to avoid undesirable harmonics fed back into the line supply, regenerative feedback when braking and for an increased degree of ruggedness with respect to line supply fluctuations.
