Table E.1 - Fault Codes
CODE DISPLAY DESCRIPTION
F00001 IET
(OVERCURRENT)
Armature current instantaneously exceeded 180% of MAXIMUM
CURRENT .
Possible causes:
•
Incorrect armature current feedback scaling (MOTOR RATED ARM
AMPS, MAXIMUM CURRENT, CT TURNS RATIO and/or J18 not set
properly).
•
One or more thyristors not operating.
•
Improper Current Minor Loop tuning.
•
Motor armature winding damaged.
F00002 TACHOMETER
LOSS
Tachometer feedback signal missing.
Possible causes:
•
Tachometer coupling failure.
•
Disconnected, loosely connected, or damaged tachometer wires.
•
Pulse encoder supply voltage low.
•
Incorrect tachometer polarity.
•
Incorrect analog tachometer scaling.
•
Incorrect pulse encoder configuration.
•
Motor armature winding not connected or open circuit.
•
Blown inverting fault (DC) fuse.
•
Inverting fault breaker tripped.
•
Tachometer failure.
•
Excessive armature voltage at motor speed <5% of TOP SPEED,
Refer to Appendix B, TACH LOSS SCR ANGLE (P608).
F00003 OVERSPEED Motor speed exceeded the 110% of TOP SPEED .
Possible causes:
•
Incorrect tachometer scaling.
•
Blown field supply fuse(s).
•
Improper speed loop tuning.
•
PULSE TACH QUADRATURE set to ON for a non-regenerative drive.
•
Incorrect pulse encoder wiring.
F00004 FIELD CURRENT
LOSS
The field loss detection circuit does not sense any field current flowing
in the motor shunt field.
Possible causes:
•
Motor field winding not connected or open circuit.
•
Blown field supply fuse(s).
•
Blown AC line fuse(s).
•
Field supply failure.
•
Disconnected, loosely connected or damaged wiring harness.
F00005 SUSTAINED
OVERLOAD
Inverse time overload circuit trip.
Possible causes:
•
Incorrect armature current feedback scaling (MOTOR RATED ARM
AMPS, MAXIMUM CURRENT, CT TURNS RATIO and/or J18 not set
properly).
•
Blown field supply fuse(s).
•
Mechanical binding preventing the motor shaft from rotating freely.
