Lower-Limit Frequency
Program  Fundamental 1
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 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 name-
plated frequency of the motor.
V/f Pattern
Program  Fundamental 1
This function establishes the relationship between the output frequency and the
output voltage.
The Automatic Torque Boost and the Sensorless Vector Control selections use
the motor tuning parameters of the ASD 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 — Variable Torque
2 — Automatic Torque Boost
3 — Sensorless Vector Control (Speed)
5 — V/f 5-Point Curve
6 — PM Drive
7 — PG Feedback Vector Control (Speed)
9 — Auto Power Save
10 — Dynamic Power Save
Note: When operating in the Vector Control mode the carrier frequency
should be set to 2.2 kHz or above.
