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 mode (sensorless or feedback).
Note:
This setting may not be higher than the Maximum Frequency
) setting.
(F011
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 setting determines the frequency at which the
output voltage of the ASD reaches its maximum setting. The maximum
voltage setting cannot be more than the input voltage (see Maximum
Output Voltage at F306). There are four Base Frequency profile settings:
1 – 4.
Note:
For proper motor operation, the Base Frequency is normally set
for the name-plated frequency of the motor.
Note:
Not used with the W7B ASD.
