EFB PROTOCOL
• Poor connections and/or noise on line.

Fault in the motor circuit. One of the motor phases is lost. Check for and
correct:
• Motor fault.
• Motor cable fault.
• Thermal relay fault (if used).
• Internal fault.
Possible power wiring error detected. When the drive is not running it
monitors for an improper connection between the drive input power and the
drive output. Check for and correct:
• Proper input wiring – line voltage is NOT connected to drive output.
• The fault can be erroneously declared if the input power is a delta
grounded system and motor cable capacitance is large. This fault can be
disabled using parameter 3023
The drive cannot use the software.
• Internal fault.
• The loaded software is not compatible with the drive.
• Call support representative.
Drive control board is overheated. The fault trip limit is 88 °C. Check for and
correct:
• Excessive ambient temperature.
• Fan failure.
• Obstructions in the air flow.
Condition defined by parameter 3701
longer than the time defined by 3703
Error internal to the drive. Contact your local ABB representative and report
the error number.
