[Parameter setting]
	Title		Function	Adjustment range	Default setting
			Drooping gain [Note]	~ %
		Speed at drooping gain 0%		~ Hz
		Speed at drooping gain		~ Hz
			Drooping insensitive torque	~ %
			Drooping output filter	~ rad/s

Note: Drooping gain can be changed within a range of 0.1 to 100.0% during operation. When changing the setting to 0.0 (no drooping) or 0.0, stop operation.

• Drooping control can be performed only when is set to , , or .

• When torque over the insensitive torque is applied, the frequency is decreased (during power running) or increased (during regenerative braking).

• The drooping function is operative at frequencies over the frequency set with .

• In the frequency range between the frequencies set with and , the degree of drooping changes according to the magnitude of frequency.

• The error in drooping insensitive torque increases in the frequency range above the base frequency, and it is

	6	therefore recommended that these functions be used at frequencies below the base frequency.
	6	• During drooping control, the output frequency is not restricted by the maximum frequency ().

		The change in frequency at the time of drooping can be calculated, as described below:

a)Gain by internal torque reference (Gain1) If internal torque reference (%) # 0

Gain1 = (internal torque reference - dead band

) / 100

Gain1 needs to be set at 0 or a positive number.

If internal torque reference (%) < 0

Gain1 = (internal torque reference + dead band

) / 100

Gain1 needs to be set at 0 or a negative number.

b) Gain by frequency after acceleration (Gain2)

If

<

Frequency after acceleration

Frequency 1 set with

Gain2 = 0

Frequency after acceleration > Frequency 2 set with

Gain2 = Drooping gain

/ 100

If frequency 1

< Frequency after acceleration

Frequency 2

Drooping gain

( Frequency after acceleration – Frequency 1

)

Gain2 =

×

100

(Frequency 2

– Frequency 1

)

If

#

Frequency after acceleration

Frequency 1 set with

Gain2 = 0

If Frequency after acceleration > Frequency 1

Gain2 = Drooping gain

/ 100

c) Drooping speed

Note × Gain1 × Gain2

Drooping speed = base frequency

Note:If the base frequency exceeds 100 Hz, count it as 100 Hz.
