F00060
SELF TUNING FAULT
Self tune aborted by external input.
Possible causes:
•
Operator stop asserted.
•
Drive interlock(s) open.
•
Drive fault became active.
F00061
SELF TUNING FAULT
Non-zero speed feedback at self-tune start.
Possible causes:
•
Analog tachometer only:
ANALOG TACH ZERO ADJ
(P.202) not set properly.
•
Incorrect speed feedback scaling or offset.
•
Overhauling load causing motor shaft rotation.
F00062
SELF TUNING FAULT
Calculated armature inductance is out of range.
Possible causes:
•
Motor armature winding not connected or open circuit.
•
Blown inverting fault (DC) fuse.
•
Inverting fault breaker tripped.
•
Armature inductance too high. Tune current minor loop manually.
F00063
SELF TUNING FAULT
Maximum current with minimum rotation.
Possible causes:
•
Motor cannot rotate freely.
•
Motor load is too high.
•
Motor field not at normal operating temperature.
F00064
SELF TUNING FAULT
Attached inertia is out of range.
Possible causes:
•
Maximum self-tune speed reached.
•
Overhauling load present.
•
High mechanical friction present.
•
The speed loop cannot be self-tuned. Tune speed loop manually.
