DESCRIPTION
F00012
ARMATURE OVER
VOLTAGE
Armature voltage exceeded 130% of
MOTOR RATED ARM VOLTS (P.009)
.
Possible causes:
•
MOTOR RATED ARM VOLTS
not set properly.
•
Improper voltage loop tuning.
F00013 NETWORK
COMMUNICATION
TIMEOUT
Network Communications is missing or failed to communicate with
master. (
CONTROL SOURCE SELECT
set to
NETWORK
)
Possible causes:
•
NETW CONNECT TYPE (P.910)
was changed from
BASIC
to
FULL
.
•
NETW DROP NUMBER
(P.900)
was changed.
•
Network Option cable connections are loose or not connected.
•
Network Option board failed or master communications failed.
F00014 REVERSED TACH
LEADS
The difference between the speed reference and speed feedback was
greater than
TACH LEAD FLT THRESH (P.227)
for the time
specified in
TACH LEAD FLT DELAY
(P.228)
.
Possible causes:
•
Tachometer or encoder leads are reversed.
•
The motor armature leads are reversed.
•
The motor field leads are reversed.
•
There is an overhauling load
•
The drive was not tuned properly.
F00015 INVERTING FAULT
AVOIDED
The inverting fault
avoidance logic has detected conditions that could
have caused an inverting fault. The drive took action to avoid an actual
inverting fault.
F00016 PHASE LOSS
PHASE LOSS DETECT EN
(P.609)
is set to
ENABLE
and the measured AC
line voltage fell below 75% of the value specified by
NOMINAL AC LINE
VOLTS (P.307).
F00017 kit missing or
unsupported kit
installed
The I/O Expansion board and Field Current Regulator are standard
equipment, and are required. The drive does not support the DeviceNet
kit.
F00030
to
F00041
SCR No. n
NOT OPERATING
The value of `n' indicates the SCR that is not operating;
n = 1-6, 11-16.
F00042 MULTIPLE SCRS
NOT OPERATING
One or more thyristor (SCR) is not carrying an equal load.
Possible causes:
•
Disconnected, loosely connected or damaged thyristor gating circuit.
•
Blown AC line fuse(s).
•
Improper current minor loop tuning.
•
Improper speed/voltage loop tuning.
•
Failed thyristor.
F00060 SELF TUNING
FAULT
Self Tune aborted by external input.
Possible causes:
•
Operator stop asserted.
•
Drive interlock(s) open.
•
Drive fault became active.
