to No.

V/f Profile - % PFL

Volts/Hertz adjustment 0 to 100% 20%

This function is available in variable torque mode and if the

Energy Economizer (Energy Savings) function (nld) is

disabled.

This parameter is useful in applications where the user

wishes to define the volts/hertz profile manually instead of

having the drive controller perform this function with the

Energy Economizer function. The 100% setting provides a

linear V/Hz output from 0–FrS (nominal motor frequency).

On the 125–500 hp drive controllers, Preset Speeds and Jog are also available. See

Tables 7 and 8 for descriptions of these functions. IR Compensation appears on 125–

500 hp drive controllers if the Special Motor parameter, SPC, is set to Yes in Menu 3.
