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
            operation
-          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
  • Available: IP54/UL protection class 12 optional (0.75~22kW[1~30hp]) *
  • Integrated RS485 communication (LS Bus / Modbus RTU)
  • Integrated transistor for dynamic braking (0.75~22kW[1~30hp])
  • Optional integrated EMV filter and DC-reactor:
