TECO A510s - PM Motor Auto-Tuning Error; Auto-Tuning Fault and Corrective Actions for PM Motor

10-17
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 information during tuning, cause and corrective action.

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 capacity
02 PG option missing.

Magnetic pole cannot be
aligned without PG option
card.
 Install PG feedback
card.
03
Magnetic pole

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
magnetic pole
alignment
(rotational
auto-tune).
 Motor cannot operate at
low speeds.

Current out of range
during circuit tuning.

Inverter output current
does not match motor
current.

Check the motor tuning
data (22-02).
 Check inverter capacity
10
Magnetic pole
alignment and
circuit tuning failed.
 Auto-tuning is not
successful.
 Retry magnetic pole
alignment and circuit
tuning.
