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.
