6 Protective Function

6-1 List of protective functions

When the protective function is activated, drive output is instantly cut off (while the motor coasts until it is stopped), and an alarm is issued, and the details of the alarm are displayed on the keypad panel.

	Undervoltage	LU	If the DC voltage of the main circuit falls below the undervoltage detection level
			because of a lowered power supply, output is shut down to protect the drive. If the
			restart function after momentary power failure is not activated, an alarm is issued
			and the drive is tripped.
			If the restart function is activated, the drive restarts automatically with no alarm.
