FLUX OPTIMIZATION
0=OFF, 1=ON
Changes the magnitude of the flux depending on the actual load. Flux
Optimization can reduce the total energy consumption and noise, and
should be enabled for drives that usually operate below nominal load.
0 =
OFF
– Disables the feature.
1 =
ON
– Enables the feature.
2602
FLUX BRAKING
0=OFF, 1=ON
Provides faster deceleration by raising the level of magnetization in the
motor when needed, instead of limiting the deceleration ramp. By
increasing the flux in the motor, the energy of the mechanical system is
changed to thermal energy in the motor. The flux braking works in
vector control mode only, i.e. when parameter 9904
