3.7 What special features does the iS7 frequency inverter have?

In addition to the extensive parameters described on the datasheet, the iS7 is also available with IP54 protection up to 22kW.

-          Constant torque / variable torque for normal load and heavy load
-          V/f and V/f PG control, sensor free vector control, vector control with
            selectable sensors
-          150 MIPS high-speed DSP    

-          Excellent performance and advanced functions:

  • Droop control (torque control)
  • KEB protection (kinetic energy buffering: kinetic energy storage) ride through protection 
  • (Delay of the under-voltage trip) under load trip protection (under-load trip)
  • PMSM (permanent magnet synchronous motor) function vector control without feedback
  • Power braking & flux braking function automatic adjustment: autotuning of static motor parameters
  • Easy to use:
    • Simple starting mode, user and macro group, multifunctional control panel
    • Sensor free control and parameter setting of the second motor
