10.4. Auto-tuning Error
When a fault occurs during auto-tuning of a standard AC motor, the display will show the “AtErr” fault and the
motor stops. The fault information is displayed in parameter 17-11.
Note: The fault contact output does not energize with an auto-tuning fault. Refer to Table 10.4.1, for fault infor-
mation during tuning, cause and corrective action.
Table10.4.1Auto-tuningfaultandcorrectiveactions
Error Description Cause Corrective action
01 Motor data input error. • Motor Input data error during auto-tu-
ning.
• Inverter output current does not match
motor rated current.
• Check the motor tuning data (17-00 to
17-09).
• Check inverter
size
02 Motor lead to lead resistance R1 tuning
error.
• Auto-tuning is not completed within the
specified time
• Auto-tuning results fall outside parame-
ter setting range.
• Motor rated current exceeded.
• Motor was disconnected.
• Check the motor tuning data (17-00 to
17-09).
• Check motor connection.
• Disconnect motor load.
• Check inverter current detection circuit
and DCCTs.
• Check motor installation
03 Motor leakage inductance tuning error.
04 Motor rotor resistance R2 tuning error.
05 Motor mutual inductance Lm tuning error.
07 Deadtime compensation detection error
06 Motor encoder error • PG feedback noise • Check motor rated current.
• Check PG card grounding.
08 Motor acceleration error (Rotational type
auto-tuning only).
• Motor fails to accelerate in the specified
time (00-14= 20sec).
• Increase acceleration time (00-14).
• Disconnect motor load
09 Other • No load current is higher than 70% of the
motor rated current.
• Torque reference exceeds 100%.
• Errors other than ATE01~ATE08.
• Check the motor tuning data (17-00 to
17-09).
• Check motor connection.
10.5. PM Motor Auto-tuning Error
When a fault occurs during auto-tuning of a PM motor, the display will show the “IPErr” fault and the motor
stops. The fault information is displayed in parameter 22-18.
Note: The fault contact output does not energize with an auto-tuning fault. Refer to Table 10.5.1, for fault infor-
mation during tuning, cause and corrective action.
Table10.5.1Auto-tuningfaultandcorrectiveactionsforPMmotor
Error Description Cause Corrective action
01 Magnetic pole alignment tuning failure
(static).
• Inverter output current does not match
motor current.
• Check the motor tuning data (22-02).
• Check inverter
size
02 PG option missing. • Magnetic pole cannot be aligned without
PG option card.
• Install PG feedback card.
03 Magnetic pole alignment auto-tuning abort
during rotational auto-tune.
• System abnormality during magnetic
pole alignment.
• Check for active protection functions
preventing auto-tuning.
04 Timeout during magnetic pole alignment
during rotational auto-tune.
• Motor cannot rotate • Check motor.
• Check motor wiring.
• Check brake released.
05 Circuit tuning time out. • System abnormality during circuit
tuning.
• Check for active protection functions
preventing auto-tuning.
06 Encoder error • PG feedback noise • Check motor rated current.
• Check PG card grounding.
07 Other motor tuning errors. • Other tuning errors. • Check the motor tuning data (22-02).
• Check motor connection
08 Motor current out of range during magnet-
ic pole alignment (rotational auto-tune).
• Motor cannot operate at low speeds. • Check PG card wiring
• Check motor connection.
09 Current out of range during circuit tuning. • Inverter output current does not match
motor current.
• Check the motor tuning data (22-02).
• Check inverter
size
10 Magnetic pole alignment and circuit tuning
failed.
• Auto-tuning is not successful. • Retry magnetic pole alignment and
circuit tuning.
