W7B ASD Installation & Operation Manual
V/f Pattern
Program Fundamental Frequency Settings
This function establishes the relationship between the output frequency
and the output voltage.
Settings:
0 — Constant Torque
1 — Variable Torque
2 — Automatic Torque Boost
3 — Sensorless Vector Control (Speed)
4 — Automatic Torque Boost with Automatic Energy Savings
5 — Sensorless Vector Control (Speed) with Automatic Energy
Savings
6 — V/f Five-Point Setting (Opens Five-Point Setting Screen)
7 — Sensorless Vector Control (Speed/Torque Switching)
8 — PG Feedback Vector Control (Speed/Torque Switching)
9 — PG Feedback Vector Control (Speed/Position Switching)
Note:
For proper operation, the Carrier Frequency must be 2.2 kHz or
above except when operating in the Constant Torque, Variable Torque,
or the Five-Point Setting modes.
The Automatic Torque Boost and the Sensorless Vector Control
selections use the motor tuning parameters of the drive 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.
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.
