BLAST-AT frequency converter


The BLAST-AT converters are utilized to control many processes and require various control capabilities per the application.

Use of BLAST-AT

This drive was designed to fulfill many applications including the following.
  • pumps - centrifugal, positive displacement
  • fans - forced and induced draft, centrifugal, axial evaporators
  • mixers, agitators, conveyors, winders, centrifuges, extruders, compressors
  • machinery for paper, steel and textile industries
  • ifts, elevators, cranes and hoists

Features

  • Auto Tuning - tunes the BLAST-AT to the motor specifications and the load
  • Speed Profile - controls the minimum/maximum speed profile for requirements
  • PID control - controls process with and internal PID loop controller
  • Energy Saver - saves energy at lower speeds of operation
  • Overload setting - protection designed to protect the motor
  • Flying Re-Start - function used to catch s spinning motor
  • Fast STOP- fast deceleration of the motot fast stop ramp rate
  • Auto ON/OFF via the input control signal, the drive can be START/STOP
  • Auto ON/OFF pomocí vstupního řídícího signálu, pohon může provést START/STOP
  • Auto Restart
  • JOG function
  • minimum/maximum speed setting

Control modes

  • V/Hz mode
  • Sensorless vector mode
  • Vector control mode
