Parameters
Overcurrent prevention function (Pr. 662)
● The overcurrent prevention function is valid under V/F control and Advanced magnetic flux vector
control.
● Increased magnetic excitation rate is lowered automatically when the output current exceeds Pr.
662 at the time of increased magnetic excitation deceleration.
● When the inverter protective function (E.OC , E.THT) operates due to increased magnetic excita-
tion deceleration, adjust with Pr. 662.
● Overcurrent preventive function will be disabled when Pr. 662= "0".
NOTE When set to Pr. 662 > Pr. 22 "Stall prevention operation level", overcurrent preventive function will
operate at the setting value of Pr. 22. (Operates at Pr. 622 when Pr. 22 = "0")
