*The VI/II input terminal can also be used.

Notes

For upper limit frequency the analog input will limit the upper limit frequency in the range 0 - UL[Hz]. If the analog input receives 4[mA] or 0[V], the upper limit frequency will be 0[Hz]. If the analog input receives 20[mA] or 10[V] the upper limit frequency will be set by Upper Limit in Program → Fundamental Parameters →Frequency Settings. Intermediate inputs will result in a linear setting of the upper limit frequency by the formula

Upper limit Frequency =	 ( X − 4)[mA]			X[V ] 
					
	UL*		Or		
		24[mA]
				10[V ] 

Where X is the input analog input in either mili-Amps or Volts. Note: accel/decel times are still calculated with reference to Maximum Frequency.

Acceleration/Deceleration Time Adjustment - The analog input will determine a multiplier to the Accel/Decel #1 parameters set in Program → Fundamental Parameters →Accel/Decel #1 Settings. With a minimum input resulting in a multiplier of 1 and a maximum input resulting in a multiplier of 10 with intermediate inputs giving a linear multiplier between 1 and 10.

Torque Boost Adjustment – The analog input will determine the percentage of Torque Boost that the drive will output at low speeds in a manner similar to that mentioned in the description of upper limit frequency discussed above.
