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)"

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.
