V/F Control Frequency (Voltage) (Pr. 100 To Pr. 109) - Mitsubishi Electric FR-A500 Instruction Manual

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.

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).
