Upper-Limit Frequency

Program Fundamental Frequency Settings
This parameter sets the highest frequency that the ASD will accept as a
frequency command or frequency setpoint. The ASD may output frequencies
higher than the Upper-Limit Frequency (but, lower than the Maximum
Frequency) when operating in the PID Control mode, Torque Control mode,
or the Vector Control modes (sensorless or feedback).
Note: This setting may not be higher than the Maximum Frequency
(F011) setting.

Lower-Limit Frequency

Program Fundamental Frequency Settings
This parameter sets the lowest frequency that the ASD will accept as a
frequency command or frequency setpoint. The ASD will output frequencies
lower than the Lower-Limit Frequency when accelerating to the lower-limit or
decelerating to a stop. Frequencies below the Lower-Limit may also be output
when operating in the PID Control mode, Torque Control mode, or the
Vector Control modes (sensorless or feedback).

Base Frequency 1

Program Fundamental Motor Set 1
The Base Frequency 1 setting is the frequency at which the output voltage of
the ASD reaches its maximum setting. The Base Frequency Voltage 1
parameter is set at F409.
For proper motor operation, the Base Frequency should be set for the
nameplated frequency of the motor.

V/f Pattern

Program Fundamental Frequency Settings
This function establishes the relationship between the output frequency and the
output voltage.
Bolded selections use the motor tuning parameters of the drive to properly
configure the ASD for the motor being used. If Load Reactors or Long Lead
Filters are used, or if the capacity of the ASD is greater than the motor, manual
tuning of the motor parameters may be required for optimum performance.
Settings:
0 — Constant Torque
1 — Voltage Decrease Curve
