This function establishes the relationship between the output frequency and the output voltage.

Settings:

Constant Torque

Variable Torque Automatic Torque Boost Sensorless Vector Control (speed)

Auto Torque Boost with Automatic Energy Savings

Sensorless Vector Control (speed) with Automatic Energy Savings V/f 5-Point Setting (opens 5-point setting screen)

Sensorless Vector Control (speed/torque switching) PG Feedback Vector Control (speed/torque switching) PG Feedback Vector Control (speed/position switching)

Direct Access Number — F015

Parameter Type — Selection List

Factory Default — Constant Torque

Changeable During Run — No

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 5-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.
