Related Functions: FU2-22 ~ FU2-25 [Speed Search]

FU2-22: Speed Search Selection (Bit Set)

FU2-23: Current Limit Level During Speed Search

FU2-24: P Gain During Speed Search

FU2-25: I Gain During Speed Search

This function is used to permit automatic restarting after Power ON, Fault Reset, and Instant Power Failure without waiting for the motor to stop.

The speed search gain should be set after considering the inertia moment (GD2) and magnitude of torque of the load. FU2-37 [Load

Inertia] must be set at the correct value to make this function operate correctly.

	Setting Range				Description
4th bit		3rd bit	2nd bit	1st bit
0		0	0	0	Speed search function does not work
0		0	0	1	Speed search during Accelerating
					Speed search during a Fault Reset
0		0	1	0	restarting (FU2-21) and Auto restarting
					(FU2-26)
0		1	0	0	Speed search during Instant Power

When FU2-22 is set to ‘1111’, Speed Search works for all conditions.

FU2-22[Speed Search Selection] selects the speed search function.

FU2-23[Current Limit Level] is the current that the inverter limits its current rise during speed searching. (The set value is the percentage of FU2-33 [Rated Motor Current])

FU2-24[P Gain] is the proportional gain used for speed search. Set this value according to load inertia set in FU2-37.

FU2-25[I Gain] is the Integral gain used for speed search. Set this value according to load inertia set in FU2-37.
