Torque Performance Modes 2-163
This curve is intended for applications such as fans and pumps where the
load increases as the speed increases. This mode is intended to have a V/Hz
profile that more closely matches the developed torque to the load torque.
Sensorless Vector
In sensorless vector control the drive maintains a consistent magnetizing
current up to base speed, the output voltage increases as a function of load.
