BLG-BC2 series

Integrated screw and motor pulse counter for process control

Features

  • Intgrated motor pulse counter
    Detects misplaced screws in realtime with a high precision thanks to the control of the motor pulses
  • Tool-teach-mode
    This allows the screwdriver to automatically recognize the pulse numbers of the motor from the beginning of tightening the screws, until they are seatet
    (min. / max. values). The reference values of pass / fail can be set with the permisible range of ± 0 to ± 20% starting at the min. / max. values
  • Error detection
    Screws that were once difficult to judge visually, (misplaced screws of different type or length, recessed screws or floating screws due to seized cables) are now detected.
  • Optional available: Controller and process documentation
