(Without digital display speed- and load condition)


  • High performance in a compact design
  • The HFU-190 allows rotational frequencies up to 1000Hz / 60.000 Upm
  • A digital signal processor (DSP) is catching all the operating parameters in real time and controls it in dependence on the load through a vector control function
  • Allows highest efficiency of the engines at low and high frequencies
  • High reliability: All operating conditions such as acceleration, operation at rated speed, and deceleration are monitored and critical states are absorbed
  • Controlled braking of the motor / spindle even with emergency stop
  • Integrated braking resistor
    Control: The converter can be controlled manually by two front keys as needed
  • Individual adaptation to the respective application and attached spindle by freely programmable characteristic spindle curves. 16 spindle characteristics curve can be created and stored
  • Diverse control and communication options
  • Simple and flexible integration into existing systems through open configuration of I / O signals for control and configuration
  • Galvanic isolation among all interfaces and from the net and motor potential
  • Short-circuit proof
  • Different housing variants are possible
