9.2 – SPECIAL PARAMETERS
P2.5.4.9.1/2/3/4 These parameters should only be modified when advised by SMS.
P2.5.4.9.5: Speed derivative
P2.5.4.9.6: Derivative filter time
These are the parameters of the derivative gain used to adjust the speed transitions, to avoid, for example,
the stop and restart of the motor at the end of the deceleration, or the speed overshoot at the end of the
acceleration that can cause undesired over-speed, more than the lift specifications.
Values have to be set proportionally to the system’s inertia. The higher the inertia, the higher values have to
be set.
P2.5.4.9.7: RollBack Control Gain
P2.5.4.9.8: RollBack Treshold
These parameters are useful to avoid the “rollback” of the motor at starting, when the brake opens.
Generally the default values work fine: too high values can cause noises and jerks at starting, too low values
can cause an undesired “rollback”.
