Protections & self – diagnostic

All our products are equipped with protection against various abnormalities with clear indications. Various alarm levels programmable through serial line include:

  • Excessive/Insufficient three-phase line voltage
  • Phase currents unbalancing (fuse failures/current ripples)
  • External/Internal motor protection (over-loading, thermal etc.)
  • Unbalancing between reference and motor speed
  • Unbalancing between armature voltage and speed
  • Synchronism ramp error
  • Thyristor firing pulse error
  • EEPROM writing error, wrong parameters
