Auto-Tuning Fault Detection

When the Auto-Tuning faults shown below are detected, the fault is displayed on the operator and the motor coasts to a stop.
Auto-Tuning faults do not trigger a multi-function terminal set for fault or alarm output.
An Endo error indicates that although Auto-Tuning has successfully completed, there is some discrepancy in the calculations.
If an Endo error occurs, check for the cause of the error using the table in this section, and perform Auto-Tuning again or
manually set the motor parameters after fixing the problem. Start the application if no problem can be diagnosed despite the
existence of the Endo error.

Auto-Tuning Codes, Causes, and Possible Solutions

HOA Keypad Display
End3
Cause
The correct current rating printed on the motor
nameplate was not entered into T1-04
HOA Keypad Display
End4
Cause
The calculated slip is outside the allowable range Make sure the data entered for Auto-Tuning is correct.
HOA Keypad Display
End5
Cause
The calculated resistance value is outside the
allowable range
HOA Keypad 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
HOA Keypad 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
Motor rated current and detected no-load current
are inconsistent
Base frequency and motor rated speed (T1-05 and
T1-07) do not match
HOA Keypad Display
Er-02
Cause
An alarm was triggered during Auto-Tuning

Table 6.12 Auto-Tuning Codes, Causes, and Possible Solutions
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
Resistance Tuning Error
• Double-check the data 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 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.
• Restart Auto-Tuning and enter the correct information.
• Check the drive and motor capacities.
• Correct the settings of parameters T1-02 and T1-04.
• Check the motor rated current and no-load current.
• Correct the settings of parameters T1-04 and E2-03.
• Correct the settings of parameters T1-05 and T1-07.
• Check that the correct number of poles were entered to T1-06.
Minor Fault
Exit the Auto-Tuning menu, check the alarm code, remove the alarm cause, and repeat Auto-Tuning.
