  • 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 infeed / 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

A Range of Formats to Meet Virtually Every Need
