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.
