z Automatic restart after instantaneous power failure (Pr. 57, Pr. 58, Pr. 162 to Pr. 165)
Pr. 57 "coasting time for automatic restart after instantaneous power
failure/commercial power supply-inverter switch-over"
Pr. 58 "cushion time for automatic restart after instantaneous power
failure/commercial power supply-inverter switch-over"
Pr.162 "Automatic restart after instantaneous power failure selection"
Pr.163 "First cushion time for restart"
Pr.164 "First cushion voltage for restart"
Pr.165 "Restart stall prevention operation level"
z You can restart the inverter without stopping the motor (with the motor coasting) when the commercial
power supply is switched to the inverter operation or when the power is restored after an instantaneous
power failure. (When automatic restart operation is set to be enabled, UVT and IPF among the alarm
output signals will not be output at occurrence of an instantaneous power failure.)
