FIELD LOSS FAULT

Was bedeutet 905 ?

The field current feedback has dropped below 80% of the expected current during specific operating conditions: Field Weakening Mode (Top speed, #49), Full Field Mode (Accel or Decel, #50), or Standing Field Mode (not running, #53). This fault will shut down the drive.

• Open circuit failure of motor field or motor field wiring.
• Hardware failure of motor field control circuitry.
• Loss of power or incorrect phasing to the Field Rectifier.
