Fuji Bikes 5000G11S/P11S U59 Braking resistor function select, U48 Input phase loss protection

◆In case of F14 set value : 3.

The output frequency is lowered by the control by which the DC voltage of the main circuit is kept constant from the regeneration energy, so that the inverter may continue operation when momentary power failure occurs.

The response is adjusted with U23 and U24 at this time.

◆Calculate the integral gain using the following formula.

Integral gain =	2	16	[ms]
	" U 23" set value

	[30HP or less is corresponded]

◆When function code F13 (electronic thermal)is set to 2, both the type of the braking resistor and connection circuit are set. Factory setting is set to nominal applied resistor and the number of resistor is one. When the power load capacities of resistor are increased, set the factory setting properly
