* Excessive V/f set value, motor iron core saturation coefficient fault, and rated current set alarm are displayed after the auto tuning is
completed.
End 2
Iron Core Sat
Motor Iron Core Saturation Coefficient Fault
(Rotational tuning only).
Since the motor iron
core saturation coefficient could not be auto-tuned
within the set time, tentative value is set in the iron
core saturation coefficient.
• Check the T1 parameters.
• Check motor wiring.
• Disconnect the motor from the load.
End 3
Motor FLA Err
Rated Current Set Alarm.
Motor current during
tuning was greater than the set value.
• Check E02-01.
End 4
Rated Slip Alarm
Adjusted Slip Calculation Error.
The slip that
was calculated is outside the allowable range.
• Make sure the Auto-Tuning data is correct.
• Execute Rotational Auto-Tuning instead. If not
possible, try Non-Rotational Auto-Tuning 2.
End 5
TermResistAlarm
Resistance Tuning Error.
The resistance value
that was calculated is outside the allowable range.
• Double check the data that was entered for the
Auto-Tuning process.
• Check the motor and wire connection for
damage.
End 6
Leakage L Alarm
Leakage Inductance Alarm.
The leakage
inductance value that was calculated is outside
the allowable range.
• Double check the data that was entered for the
Auto-Tuning process.
End 7
No-Load I Alarm
No-Load Current Alarm.
The entered no-load
current value was outside the allowable range, or
Auto-Tuning results were less than 5% of the
motor current.
• Check and correct faulty motor wiring.
• Double check the data that was entered for the
Auto-Tuning process.
