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).
Direct Access Number — F013
Parameter Type —
Numerical
Factory Default —
0.00
Changeable During Run —
Yes
Minimum — 0.00
Maximum — Upper-Limit Freq. (
F012
)
Units — Hz
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.
Direct Access Number — F014
Parameter Type —
Numerical
Factory Default —
(ASD-Dependent)
Changeable During Run —
No
Minimum — (ASD-Dependent)
Maximum — (ASD-Dependent)
Units — Hz

Fundamental
Frequency Settings
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 — Voltage Decrease Curve
2 — Automatic Torque Boost
3 — Sensorless Vector Control (Speed)
5 — V/f 5-point Curve (Go to
F190
to configure the V/f 5-Point Settings)
6 — PM Drive (Permanent Magnet)
7 — PG Feedback Vector Control (Speed)
9 — Energy Savings
10 — Advanced Energy Savings
Note:
When operating in the
Vector Control
mode, the carrier
frequency should be set to 2.2 kHz or above.
