5.3.7 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. Refer to Table 10.4.1,
for fault information during tuning, cause and corrective action.
Table 3 Auto-tuning fault and corrective actions
Error Description Cause Corrective action
01 Motor data input error.

Motor Input data error during
auto-tuning.

Inverter output current does not
match motor rated current.

Check the motor tuning data
(17-00 to 17-09).

Check inverter capacity
02
Motor lead to lead
resistance R1 tuning error.

Auto-tuning is not completed
within the specified time

Auto-tuning results fall outside
parameter setting range.

Motor rated current exceeded.

Motor was disconnected.

Check the motor tuning data
(17-00 to 17-09).

detection error
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 auto-tuning errors


5.3.8 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 22-22. Refer to Table 4 for fault
information during tuning, cause and corrective action.
