Mitsumi electronic FR-F520-0.75K, 55K 38 V/F control frequency voltage Pr to Pr, Parameter Number

PARAMETERS

4.2.38 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)"

Related parameters

Pr. 19 "base frequency voltage"

Pr. 47 "second V/F (base frequency)" Pr. 60 "intelligent mode selection" Pr. 71 "applied motor"

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.
