You can make setting to prevent the inverter from

an overcurrent trip (prevent the fast-

response current restriction from being activated) and/or set the OL signal output delay

if stall prevention is activated by an overcurrent or an excessive current flows due to

sudden fluctuation of load, ON-OFF of the running inverter output side or the like.
