When frequency and parameter “P103 to P105” are set to “digital setting with operation panel (P004 = 1)” and “20” respectively, SW3 and SW4 can be used to change frequency while SW5 is used to save this frequency.

· SW3: During ON, frequency increases. (During OFF, the existing frequency is held.)

· SW4: During ON, frequency decreases. (During OFF, existing frequency is held.)

· SW5: Turn ON once and OFF again to save the frequency at that time.

(The frequency can be saved even if the power is turned OFF.)

■ Speed Search Function

· The inverter will apply minor DC voltage to the motor, detect its rotation speed and restart it at this frequency when the motor rotates freely due to inertia, which is the so-called “speed search function”.

· There are 3 methods to start the speed search.

1) Through input signal from control terminals (SW1 to SW6)

Related parameters: P101 to P106 (SW1 to SW6 Function Selection)

· If the rotation speed is too low and the rotation direction does not match the rotation command, the rotation speed may not be sensed.

· The sensing function may fail if the speed search is performed for the motor with capacity smaller than the inverter.

Especially, when P340 is set to "3", it will be 2-point random mode, the basic frequency will change from fixed frequency to second frequency with the change of winding length. And, rise time coefficient change randomly in the random range.

· When parameter “P101 to P106: SW1 to SW6 Function Selection” is set to “13”, and SW input of corresponding control input terminals (SW1 to SW6) are ON, the inverter will terminate winding mode control and continue to run at the frequency when SW input (SW1 to SW6) is turned ON.
