V/f Pattern
Program
Fundamental
Frequency
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:
Constant Torque
Voltage Decrease Curve
Automatic Torque Boost
Sensorless Vector Control (Speed)
Sensorless Vector Control (Speed/Torque Switching)
V/f 5-Point Curve (Go to
F190
to configure the V/f 5-point settings)
PM Drive (Permanent Magnet)
PG Feedback Vector Control (Speed)
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.
Direct Access Number — F015
Parameter Type — Selection List
Factory Default — PG Feedback Vector
Control (Speed/Torque Switching)
Changeable During Run — No
Manual Torque Boost 1
Program
Fundamental
Motor Set 1
The Manual Torque Boost 1 function is used to increase the low frequency
torque for high-inertia loads by increasing the output voltage at frequencies
below ½ of the Base Frequency 1 (
F014
) setting.
The value programmed as a boost percentage establishes an output voltage vs.
output frequency relationship to be used to start the motor or to provide
smoother operation.
Note:
Setting an excessive Torque Boost level may cause nuisance
tripping and mechanical stress to loads.
Direct Access Number — F016
