Motor control variables
Activates/deactivates the flux optimization function. Flux
optimization reduces the total energy consumption and
motor noise level when the drive operates below the
nominal load. The total efficiency (motor and the drive) can
be improved by 1% to 10%, depending on the load torque
and speed. The disadvantage of this function is that the
dynamic performance of the drive is weakened.
