4.2.44 Stall prevention function and current limit function (Pr. 156)

Pr. 156 "stall prevention operation selection"
You can make setting to disable stall prevention caused by overcurrent, make setting to disable the fast-
response current limit which limits the current to prevent the inverter from resulting in an overcurrent trip if an
excessive current occurs due to sudden load variation or ON-OFF, etc. in the output side of the running
inverter, and set the OL signal output delay.
