Digital Operator Copy Function Faults

These faults can occur during the digital operator COPY function. When a fault occurs, the fault content is dis-
played on the operator. A fault does not activate the fault contact output or alarm output.

was write-protected (o3-02 = 0).
IFE The data file read from the Inverter was of
the wrong size indicating corrupted data.
RDE An attempted writing of the Inverter data to
DATA ERROR the Digital Operator's EEPROM failed.
Table 7.4 Auto-tuning Faults
Probable causes
Auto-tuning was not completed in
the specified time.
Auto-tuning result is outside the
parameter setting range.
The torque reference exceeded
100% and the no-load current
exceeded 70% during auto-tun-
ing.
During auto-tuning, the measured
values of motor iron-core satura-
tion coefficient 1 and 2 (E2-07
and E2-08) exceeded its setting
range. A temporary value was set:
E2-07 = 0.75, E2-08 = 0.50
During auto-tuning, the measured
value of motor rated current
(E2-01) was greater than the set
value.
As a result of non-rotating auto-
tuning 1 the slip value was set to
0.2 Hz or below.
Probable Causes
Corrective Actions
Check motor wiring.
Check and correct the motor
settings
If the motor and the machine
are connected, disconnect the
motor from the machine.
Check the input data.
Check the motor wiring.
If the motor and the machine
are connected, disconnect the
motor from the machine.
Check the motor rated current
value.
Check the autotuning input
data
If possible perform a rotating
autotuning or non-rotating
autotuning 2.
Corrective Actions
Set o3-02 to enable writing parameters
into the Operator's memory.
Retry the READ command (o3-01 = 1).
Check the Digital Operator's cable.
Replace the Digital Operator.
A low Inverter voltage has been
detected.
Retry the READ command (o3-01 = 1).
Replace the Digital Operator.
