Alarm indications
In any mode, an alarm is an indication given on the KI-Remote Keypad
display by alternating the alarm string with the drive status string on the
first row and showing the alarm symbol in the last character in the first
row. If an action is not taken to eliminate any alarm except "Auto Tune
and Limit Switch" the drive may eventually trip. Alarms are not displayed
when a parameter is being edited, but the user will still see the alarm
character on the upper row.
