ƒ
This is used to prevent possible fault from occurring if the inverter outputs the voltage
during operation after the load is removed.
ƒ
The inverter estimates the motor rpm based on output current. Therefore, detecting exact
speed is difficult.

H23: Limits current during Speed search. Set as the percent of H33.
H24, H25: Speed search is activated via PI control. Adjust P gain and I gain
corresponding to the load characteristics.
I54, I55: Signal of active Speed search is given to external sequence via Multi-
function output terminal (MO) and Multi-function relay output (3ABC).
