<Setting>

Refer to the following table and set the parameter:

Pr. 155 Setting Description

0Made valid immediately by switching the RT signal on-off.

Made valid only when the RT signal is on at constant

10speed.

(Invalid during acceleration/deceleration)

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

Pr. 156 "stall prevention operation selection" Related parameters

Pr. 22 "stall prevention operation level" Pr. 23 "stall prevention operation level compensation factor at double

speed"

Pr. 48 "second stall prevention operation current"

Pr. 49 "second stall prevention operation frequency"

Pr. 154 "voltage reduction selection during stall prevention operation"

Pr. 157 "OL signal output waiting time"

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.
