 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.

Auto-tuning was not completed in
the specified time.
Check motor wiring.
Auto-tuning result is outside the
parameter setting range.

V/f Over Setting
V/f Settings Alarm
Displayed after auto-tuning is
complete
The torque reference exceeded
100% and the no-load current
exceeded 70% during auto-tun-
ing.
Check and correct the motor
settings
If the motor and the machine
are connected, disconnect the
motor from the machine.

Saturation
Motor Core Saturation Fault
Displayed after auto-tuning is
complete.
Detected only for rotating auto-
tuning
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
Check the input data.
Check the motor wiring.
If the motor and the machine
are connected, disconnect the
motor from the machine.

Rated FLA Alm
Rated Current Setting Alarm
Displayed after auto-tuning is
complete
During auto-tuning, the measured
value of motor rated current
(E2-01) was greater than the set
value.
Check the motor rated current
value.
End - 4
Slip Lower Limit
Adjusted slip is below lower
limit.
As a result of non-rotating auto-
tuning 1 the slip value was set to
0.2 Hz or below.
Check the autotuning input
data
If possible perform a rotating
autotuning or non-rotating
autotuning 2.

o3-01 was set to 1 to write parameter into
the Digital Operator when the Operator
was write-protected (o3-02 = 0).
Set o3-02 to enable writing parameters
into the Operator’s memory.
IFE
READ DATA ERROR
The data file read from the Inverter was of
the wrong size indicating corrupted data.
Retry the READ command (o3-01 = 1).
Check the Digital Operator’s cable.
Replace the Digital Operator.
RDE
DATA ERROR
An attempted writing of the Inverter data to
the Digital Operator’s EEPROM failed.
A low Inverter voltage has been
detected.
Retry the READ command (o3-01 = 1).
Replace the Digital Operator.
