HFI [HF inj. activation]
[No] (nO)
g
Activation of high frequency signal injection in RUN. This function allows to estimate the motor speed in a view to have torque
at low speed without speed feedback.
Note: The more the saliency is high, the more the [HF inj. activation] (HFI) function will be efficient.
In order to ensure the performances, it could be necessary to adjust the speed loop parameters ([K speed loop filter] (SFC),
[Speed time integral] (SIt) and [Speed prop. gain] (SPG), see page 105
) and the speed estimation phase locked loop
(Expert parameters [HF pll bandwith] (SPb) and [HF pll dump. factor] (SPF), see page 103
).
High frequency injection is not efficient with low saliency motors (see [Saliency mot. state] (SMOt) page 101
).
It is advised to have 4 kHz of pwm frequency ([Switching freq.] (SFr)).
In case of instability with no load, it is advised to decrease [Speed prop. gain] (SPG) and [HF pll bandwith] (SPb). Then,
adjust the speed loop parameters to have the dynamic behavior and the PLL gains to have a good speed estimation at low
speed.
In case of instability with load, it could help to increase the [Angle error Comp.] (PEC) parameter (mainly for SPM motor).
nO
YES
[No] (nO): Function deactivated
[Yes] (YES): High frequency injection is used for speed estimation

These parameters only appear if the corresponding function has been selected in another menu. When the parameters can
also be accessed and adjusted from within the configuration menu for the corresponding function, their description is detailed
in these menus, on the pages indicated, to aid programming.
T
Parameter that can be modified during operation or when stopped.
To change the assignment of this parameter, press the ENT key for 2 s.
