ACE-tronics G9 ASD Installation and Operation Manual
Maximum Frequency
Program
Fundamental
Frequency
This setting determines the absolute maximum frequency that the ASD can
output.
Accel/Decel times are calculated based on the Maximum Frequency setting.
The Maximum Frequency is not limited by this setting while operating in the
Drooping Control mode (see
F320
for additional information on this setting).
Note:
This setting may not be lower than the Upper-Limit Frequency
setting (
F012
).
Direct Access Number — F011
Parameter Type — Numerical
Factory Default — 65.0
Changeable During Run — No
Minimum — 30.0
Maximum — 299.0
Units — Hz
Upper-Limit Frequency
Program
Fundamental
Frequency
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 — 60.00
Changeable During Run — Yes
Minimum — 0.0
Maximum — Max. Freq. (
F011
)
Units — Hz
Lower-Limit Frequency
Program
Fundamental
Frequency
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 — 13.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — Upper Limit (
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
nameplate frequency of the motor.
Direct Access Number — F014
Parameter Type — Numerical
Factory Default — 60.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — Upper Limit (
F012
)
Units — Hz
