P9 ASD Installation and Operation Manual
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
(
)
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
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 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)
4 —
Sensorless Vector Control (Speed/Torque Switching)

6 — PM Drive (Permanent Magnet)
7 —
PG Feedback Vector Control (Speed)
8 —
PG Feedback Vector Control (Speed/Torque Switching)
Note:
When operating in the
Vector Control
mode the carrier
frequency should be set to 2.2 kHz or above.
