  Stall prevention from 

  overvoltage and overcurrent

The current and voltage are limited automatically during operation to prevent frequent tripping due to over-current and over-voltage.
  Rapid current limitReduce the risk of over-current faults to keep VFD operated normally.
  Torque limit and controlLimit the torque automatically during operation to prevent frequent tripping due to over-current.
  Brake unitBuilt-in braking unit for 22KW and below models
  SPECIAL FEATURES
