Description
Defines the derivation time for acceleration(/deceleration)
compensation. In order to compensate for a high inertia load
during acceleration, a derivative of the reference is added to
the output of the speed controller. The principle of a derivative
action is described under parameter
time.
Note: As a general rule, set this parameter to the value
between 50 and 100% of the sum of the mechanical time
constants of the motor and the driven machine.
The figure below shows the speed responses when a high
inertia load is accelerated along a ramp.
No acceleration compensation:

Acceleration compensation derivation time.
Defines the acceleration (or deceleration) compensation filter
time constant. See parameters
and 25.06 Acc comp derivation time.
Acceleration/deceleration compensation filter time.
Enables/disables the flux optimization function. Flux
Optimization reduces the total energy
consumption and noise when the drive operates below the
nominal load. This must be enabled for drives that usually
operate below nominal load.
Enables the flux optimization. Changes the magnitude of the
flux depending on the actual load.
Disables the flux optimization.
