for load inertia while operating in the Drooping Control mode.
	Minimum — 0
	Maximum — 100
Speed PID Switching Frequency	Direct Access Number —	F466
Program ⇒ Feedback ⇒ Feedback Settings	Parameter Type — Numerical
	Factory Default — 0.00

While running, this parameter establishes the threshold speed setting that is

used to determine if PID control may engage or remain engaged if active.

Changeable During Run — Yes

Minimum — 0.00

Maximum — Max. Freq. (F011)

Units — Hz

V/I Input Bias

Program ⇒ Frequency ⇒ Speed Reference Setpoints

This parameter is used to fine-tune the bias of the V/I input terminals.

Note: See note on pg. 43 for more information on the V/I terminal.

This setting may be used to ensure that the zero level of the input source (pot, pressure transducer, flow meter, etc.) is also the zero level setting of the ASD system.

This is accomplished by setting the input source to zero and adjusting this setting to provide an output of zero from the ASD.

Direct Access Number — F470

Parameter Type — Numerical

Factory Default — 127

Changeable During Run — Yes

Minimum — 0

Maximum — 255

V/I Input Gain

Program ⇒ Frequency ⇒ Speed Reference Setpoints

This parameter is used to fine tune the gain of the V/I input terminals.

Note: See note on pg. 43 for more information on the V/I terminal.

This setting may be used to ensure that the 100% level of the input source (pot, pressure transducer, flow meter, etc.) is also the 100% level setting of the ASD system.

This is accomplished by setting the input source to 100% and adjusting this setting to provide an output of 100% from the ASD.

Direct Access Number — F471

Parameter Type — Numerical

Factory Default — 129

Changeable During Run — Yes

Minimum — 0

Maximum — 255
