Selection of gain profile for the proportional speed control gain.
Default Setting: Variable
Setting: Description:
Variable The KP speed gain is constant according to corresponding
acceleration and deceleration settings (Typical).
Resonant For PM motors which may exhibit a torque ripple at a
resonant frequency or for elevators which may have
unresolved resonant rope issues, the proportional speed
gain control features adjustment to increase/decrease
the speed gains around a given speed/frequency. See
parameter LC21 – 24 for further information.
Default = Variable (0)
Percentage increase or decrease of the proportional speed gain at the resonant
speed defined in LC22 during acceleration.
Speed at which the increase or decrease of the resonant proportional gain in
LC21 is fully effective.
Percentage increase or decrease of the proportional speed gain at the resonant
speed defined in LC24 during deceleration.
Speed at which the increase or decrease of the resonant proportional gain in
LC23 is fully effective.
