*1 The inverter output is shut off immediately (between more than 15ms and less than 100ms) after the power is switched OFF.
If more than 100ms has elapsed after the power is switched OFF, the inverter protective circuit is automatically reset by
powering ON again.
*2 Inverter output immediately shuts off if bus voltage of inverter drops to the specified value or lower for more than 10ms after
power OFF.

starting frequency. However, automatic restart after instantaneous power failure becomes active when the automatic restart
after instantaneous power failure function [Pr.57] is set to "0" or "0.1 to 5s".
*2 An instantaneous power failure of longer than 100ms is identical to a long-time power failure. (Refer to (2) inverter power ON/
OFF timing chart.) If the start signal is ON, the inverter is restarted when the power is restored.
