INVERTER CONTROL PARAMETER
Max. Output Frequency
This parameter determines the inverters max.
output frequency.
Max. Voltage Frequency
This value should be set according to the rated
frequency of the motor.
Mid-Point Frequency
Refers to the mid-point frequency of the V/F
curve. The V/F ratio between the min. frequency
and mid-point frequency can be determined.
Mid-Point Voltage
Refers to the mid-point voltage of any V/F curve.
The V/F ratio between the min. frequency and
mid-point frequency can be determined.
Min.Output Frequency
Refers to the min. output frequency of the
inverter.
Min. Output Voltage Refers to the min. output voltage of the inverter.
Acceleration Time
Refers to the time required for the inverter
to accelerate from 0 Hz to its max. output
frequency.
Deceleration Time
Refers to the time required for the inveter to
decelerate from the max. output frequency down
to 0 Hz.
Stop Mode
1. Ramp: the inverter decelerates the motor to
min. output frequency then stops according to
the set deceleration time.
2. Coast: the inverter stops output instantly upon
command, and the motor free runs until it comes
to a complete stop.
Motor HP
Displays the inverter HP that is currently being
utilized.
Overload Rate
Refers to the trip current level against the rated
current of the motor.
Overload Time
Refers to the maintaining time of the overload
trip level to generate the overload trip.
Over-Voltage Rate
Refers to over-voltage protection.
Low-Voltage Rate
Refers to the low-voltage protection.
Carrier Frequency
Refers to the trip current level against the rated
current of the motor.
