IMPULSE®•G+ & VG+ Series 4 Instruction Manual – February 2017
6-24
End 1*
V/f Oversetting
Excess V/f setting (Rotation type tuning
only). The torque reference exceeded 100%
and no load current exceeded 70%.
• Check the T1 parameters.
• Disconnect the motor from the load.
End 2
Saturation
Motor Iron Core Saturation Coefficient
Fault (Rotation type 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
Rated FLA Alm
Rated Current Set Alarm. Motor current
during tuning was greater than the set value.
• Check E02-01.
End 4
Adjusted Slip Calculation Error. The slip
that was calculated is outside the allowable
range.
• Make sure the data entered for Auto-Tuning
is correct.
• Execute Rotational Auto-Tuning instead. If
not possible, try Stationary Auto-Tuning 2.
End 5
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 motor cable
connection for faults.
End 6
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 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.
Fault Display Fault or Indicator Name/Description Corrective Action
NOTE: * Excessive V/f set value, motor iron core saturation coefficient fault, and rated current set alarm are displayed after the auto tuning is
completed.
