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
