Product information

The HFU-3200 is a frequency converter available in an extremely compact design. With the Zwanzig spindle controller software the parameterization of the converter can be managed easily and comfortably. For connection between PC and converters only a standard USB printer cable is necessary. In addition, the HFU-3200 has the ITM stem protection system.

Optionally, a control unit is available to control the frequency converter manually.


  • ITM (Intelligent Temperature Management) spindle protection system – motor and ball bearing protection
  • High performance in a compact design
  • 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 – lock pulse after EN954_Kat.3
    Integrated braking resistor
  • Individual adaptation to the respective application and attached spindle by freely programmable spindle curves. 16 spindle characteristics 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 between all interfaces among each other and from the mains and motor potential
  • Short-circuit proof
