The Innovative



The VF-MB1 is the first choice for drive solutions with high demands on the control characteristics and the integrated functions for applications in machine building industry, material handling or for pumps and fans.
The integrated PLC (Logic Sequence) allow the integration of control functions in the drive. With its broad range of field bus options, which are available as plug-in hardware modules, as well as the standard Modbus® RTU and CANopen® interfaces the VF-MB1 can be integrated in nearly every production environment.

  • Slim shape body (only 45 mm wide up to 1,5 kW)
  • CANopen® and Modbus® interfaces built-in
  • EMC filter C2
  • Easy configuration
  • PID control, PLC functions (Logic Sequence)
  • STO / SS1 according to IEC/EN61800-5-2
  • Dual rating (CT/VT)
