Use this function to specify whether to output [AL] Alarm signal (error output) (output terminal function
028) when an instantaneous power failure or under-voltage occurs according to [bb-27] Selection of
instantaneous power failure/under-voltage trip during stopping.
Examples 1 to 6 show cases with no retry.
Precautions for Correct Use
• When the power to control power supply terminals R0 and T0 is supplied from main power
supply terminals R, S, and T, and if the control power supply terminals continue to be shut off
for 80 ms or more, it is considered as power failure. After the power supply is recovered, the
inverter performs power-on operation.
• Depending on the load conditions of the motor driven by the inverter, an under-voltage error
[E009], instead of an instantaneous power failure error [E016], may occur.
• The inverter outputs the alarm while the power to control power supply terminals R0 and T0
remains.
