PARAMETERS

4.2.40 V/F control frequency (voltage) (Pr. 100 to Pr. 109)

Pr. 100 "V/F1 (first frequency)"

Pr. 101 "V/F1 (first frequency voltage)"

Pr. 102 "V/F2 (second frequency)"

Pr. 103 "V/F2 (second frequency voltage)"

Pr. 104 "V/F3 (third frequency)"

Pr. 105 "V/F3 (third frequency voltage)"

Pr. 106 "V/F4 (fourth frequency)"

Pr. 107 "V/F4 (fourth frequency voltage)"

Pr. 108 "V/F5 (fifth frequency)"

Pr. 109 "V/F5 (fifth frequency voltage)"

You can make a dedicated V/F pattern by using V/F (frequency Voltage/Frequency) control to set V/F

characteristics from the start to the basic frequency and basic voltage as desired.

Desired V/F characteristics can be set by presetting V/F1 (first frequency voltage/first frequency), V/F2, V/

F3, V/F4 and V/F5 in the corresponding parameters.

<Setting>

(1) Confirm the settings of Pr. 19, Pr. 60 and Pr. 71.

Description

Set the rated motor voltage.
This function is not activated if its value is "9999" and "8888" (factory setting).

Set "0" (ordinary operation mode).

Set "2" (V/F 5-point flexible characteristic).
