Table 24. LC20 Gain profile mode settings
The KP speed gain is constant according to corresponding
acceleration and deceleration settings (Typical).
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.
 Refer to parameters LC21-24 for further information.
LC21 KP Speed Resonance Acceleration
Percentage increase or decrease of the proportional speed gain at the resonant speed
defined in LC22 during acceleration.
LC22 Speed at Resonance Acceleration
Speed at which the increase or decrease of the resonant proportional gain in LC21 is fully
effective.
LC23 KP Speed Resonance Deceleration
Percentage increase or decrease of the proportional speed gain at the resonant speed
defined in LC24 during deceleration.
