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.
Error
01 Motor data input error.
02 Motor lead to lead resistance R1 tuning
error.
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
08 Motor acceleration error (Rotational type
auto-tuning only).
09 Other

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.
Error
01 Magnetic pole alignment tuning failure
(static).
02 PG option missing.
03 Magnetic pole alignment auto-tuning abort
during rotational auto-tune.
04 Timeout during magnetic pole alignment
during rotational auto-tune.
05 Circuit tuning time out.
06 Encoder error
07 Other motor tuning errors.
08 Motor current out of range during magnet-
ic pole alignment (rotational auto-tune).
09 Current out of range during circuit tuning.
10 Magnetic pole alignment and circuit tuning
failed.

Table 10.5.1 Auto-tuning fault and corrective actions for PM motor
Description
• Inverter output current does not match
motor current.
• Magnetic pole cannot be aligned without
PG option card.
