Motor speed is greater than 120% of the larger (in magnitude) of 2001
MINIMUM SPEED
• Parameter settings for 2001 and 2002.
• Adequacy of motor braking torque.
• Applicability of torque control.
• Brake chopper and resistor.
Not used.
Internal fault. Configuration Block Drive ID is not valid. Contact your local
ABB representative.
Internal configuration file has an error. Contact your local ABB
representative.
1 Fieldbus communication has timed out. Check for and correct:
ERR
• Fault setup (3018
• Communication settings
EFB PROTOCOL
• Poor connections and/or noise on line.
Error in reading the configuration file for the embedded fieldbus.
Fault trip forced by the fieldbus. See the fieldbus User's Manual.
1 Fault code reserved for the embedded fieldbus (EFB) protocol application.
The meaning is protocol dependent.

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.
Not for drives with an OMIO control board.
