HP 30 30 manual FU2-19 Input/Output Phase Loss Protection Bit Set, FU2-20 Power on Start Selection

Chapter 6 - Parameter Description [FU2]

☞Note: When the reference frequency is set inside the jump frequency, the output frequency goes to the frequency marked by “n” symbol.

☞Note: If one frequency jump range is required, set all ranges to the same range.

FU2-17: Start Curve for S-Curve Accel/Decel Pattern

FU2-18: End Curve for S-Curve Accel/Decel Pattern

FU2► Start Curve			17	40
17	40	%
Factory Default:	40%			40
FU2► End Curve		%	18	40
18	40
Factory Default:	40%			40

This parameter is used to adjust the Accel and Decel pattern when ‘S-Curve’ is selected in FU1-05 and FU1-06 respectively. To use this function, the Reference Frequency for Accel and Decel set in FU2-70 should be set to ‘Delta freq’.

Output Frequency

			Max. Freq./2
FU2-17	FU2-18	FU2-17	Time
			FU2-18
	Linear		Linear

[S0Curve Adjustment]

Actual Accel Time = DRV-01 + (DRV-01 * FU2-17)/2 + (DRV-01*FU2-18)/2

Actual Decel Time = DRV-02 + (DRV-02 * FU2-17)/2 + (DRV-02*FU2-18)/2

Ex) If DRV-10: 1 sec, FU2-17: 40%, FU2-18: 20%, Actual Accel Time = 1 sec + (1sec*0.4)/2 + (1sec*0.2)/2 = 1.3 sec

FU2-19: Input/Output Phase Loss Protection (Bit Set)

FU2► Trip select		19	00
19	00
Factory Default:	00		00

This function is used to cut the inverter output off in case of phase loss in either input power or inverter output.

FU2-20: Power ON Start Selection

FU2►Power-on run		20	0
20 --- No ---
Factory Default:	No		0

If FUN-20 is set to ‘No’, restart the inverter by cycling the FX or RX terminal to CM terminal after power has been restored.

If FUN-20 is set to ‘Yes’, the inverter will restart after power is restored. If the motor is rotating by inertia at the time power is restored, the inverter may trip. To avoid this trip, use ‘Speed Search’ function by setting FU2-22 to ‘1xxx’.
