Auto-Tuning Fault Detection

Auto-Tuning faults are shown below. When the following faults are detected, the fault is displayed on the digital operator
and the motor coasts to a stop. Auto-Tuning faults do not trigger an multi-function terminal set for fault or alarm output.
An End error indicates that although Auto-Tuning has completely successful, there is some discrepancy in the
calculations the drive made. If an End error occurs, check for what might be causing the error using the table below,
and perform Auto-Tuning again once the problem has been taken care of. If there appears to be no problem despite the
End error being displayed, go ahead and start the application.

◆ Auto-Tuning Codes, Causes, and Possible Solutions

Digital Operator Display
End1
Cause
The torque reference exceeded 20% during
Auto-Tuning.
The results from Auto-Tuning the no-load current
exceeded 80%.
Digital Operator Display
End3
Cause
The correct current rating printed on the nameplate
was not entered into T1-04.
Digital Operator Display
End4
Cause
The slip that was calculated is outside the allowable
range.
Digital Operator Display
End5
Cause
The resistance value that was calculated is outside
the allowable range.
Digital Operator Display
End7
Cause
The entered no-load current value was outside the
allowable range.
Auto-Tuning results were less than 5% of the motor
rated current.
Digital Operator Display
Er-01
Cause
Motor data or data entered during Auto-Tuning was
incorrect.
Motor output power and motor-rated current settings
(T1-02 and T1-04) do not match.
Base frequency and motor rated speed (T1-05 and
T1-07) do not match.
Digital Operator Display
Er-02
Cause
An alarm was triggered during Auto-Tuning.
Digital Operator Display
Er-03
Cause
Auto-Tuning canceled by pressing STOP button.

Table 6.13 Auto-Tuning Codes, Causes, and Possible Solutions
Excessive V/f Setting (detected only during Rotational Auto-Tuning for V/f control (T1-01 = 3), and displayed after Auto-Tuning is
complete)
• Before Auto-Tuning the drive, verify the information written on the motor nameplate and enter that data to T1-03 through T1-05.
• Enter proper information to parameters T1-03 to T1-05 and repeat Auto-Tuning.
• If possible, disconnect the motor from the load and perform Auto-Tuning. If the load cannot be uncoupled, simply use the Auto-
Tuning results as they are.
Rated Current Setting Alarm (displayed after Auto-Tuning is complete)
• Check the setting of parameter T1-04.
• Check the motor data and repeat Auto-Tuning.
Adjusted Slip Calculation Error
• Make sure the data entered for Auto-Tuning is correct.
Resistance Tuning Error
• Double check the data that was entered for the Auto-Tuning process.
• Check the motor and motor cable connection for faults.
No-Load Current Alarm
Check and correct faulty motor wiring.
Double check the data that was entered for the Auto-Tuning process.
Motor Data Error
• Check that the motor data entered to T1 parameters matches motor nameplate input before Auto-Tuning.
• Start Auto-Tuning over again and enter the correct information.
• Check the drive and motor capacities.
• Correct the settings of parameters T1-02 and T1-04.
• Set T1-05 and T1-07 to the correct value.
• Check if the correct pole number was entered to T1-06.
Minor Fault
Exit the Auto-Tuning menu, check the alarm code, remove the alarm cause, and repeat Auto-Tuning.
STOP Button Input
Auto-Tuning did not complete properly and will have to be performed again.
