z Stall prevention function and current limit function (Pr. 156)
Pr. 156 "stall prevention operation selection"
You can make a setting to disable stall prevention caused by overcurrent, make a 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.
