Flux Optimization; Settings; Acceleration And Deceleration Ramps; Constant Speeds - ABB ACS800 Series Firmware Manual

Flux Optimization

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.

Parameter

Acceleration and deceleration ramps

It is possible to adjust the acceleration/
deceleration times and the ramp shape.
The available ramp shape alternatives are
Linear and S-curve.
Linear: Suitable for drives requiring steady or
slow acceleration/deceleration.
S-curve: Ideal for conveyors carrying fragile
loads, or other applications where a smooth
transition is required when changing the speed.

Constant speeds

It is possible to predefine constant speeds. Constant speeds are selected with digital
inputs. Constant speed activation overrides the external speed reference.
