Simultaneous control of several drives

Dedrive Pro

Strong performance up to 560 kW

Our Dedrive Pro frequency inverters are high-performance components ranging from 1.5 to 560 kW for 380 to 690 V systems. They are the solution to satisfy a variety of requirements and have firmly established their position in the industry. We have developed sophisticated crane functions to meet special requirements in your company.

  • Infinitely variable motions for travel, lifting, turning and slewing applications
  • Range of outputs in seven sizes
  • Additional applications with supplementary options
  • Also available as complete application modules
