76 HX7+ ASD Installation and Operation Manual
Upper Limit Frequency
Program Fundamentals 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.
Direct Access Number — F012
Parameter Type — Numerical
Factory Default — 80.0
Changeable During Run — Ye s
Minimum — 0.0
Maximum — Max. Freq. (F011)
Units — Hz
Lower Limit Frequency
Program Fundamentals 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 — 0.0
Changeable During Run — Ye s
Minimum — 0.0
Maximum — Upper Limit (F012)
Units — Hz
Motor #1 Base Frequency
Program Fundamentals 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 that 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.
Direct Access Number — F014
Parameter Type — Numerical
Factory Default — 60.0
Changeable During Run — Ye s
Minimum — 25.0
Maximum — 299.0
Units — Hz
