Fluxoptimization reduces the total energy consumption andmotor noise level when the drive operates below thenominal load. The total efficiency (motor and the drive) canbe improved by 1% to 10%, depending on the load torqueand speed. The disadvantage of this function is that thedynamic performance of the drive is weakened.OFFOFF Inactive 0ON Active 12602 FLUXBRAKINGActivates/deactivates the Flux braking function. See sectionFlux braking on page 140.OFFOFF Inactive 0MODERATE Flux level is limited during the braking. Deceleration time islonger compared to full braking. The moderate mode isalways used with permanent magnet motor selection andvector control.1FULL Maximum braking power. Almost all available current isused to convert the mechanical braking energy to thermalenergy in the motor.2All parametersNo. Name/Value Description Def/FbEq
