TECO A510s Series - PM Motor Auto-Tuning Error

50
4.4 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 4.3, for fault information during tuning,
cause and corrective action.

4.5 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 4.4, for fault information during tuning,
cause and corrective action.
