This is used to prevent possible faults from occurring if the inverter outputs the voltage during operation after the load is removed.

The inverter estimates the motor rpm based on output current. Therefore, detecting exact speed is difficult.

H23: Limits current during Speed search. Set as a percentage of H33.
H24, H25: Speed search is activated via PI control. Adjust P gain and I gain
corresponding to the load characteristics.				￿

t32, t33: Signal of active Speed search is given to external sequence via Multi-function output terminal (MO) and Multi-function relay output (3ABC).
