Parameter Description
Ogive run with crawl path (DOL= digital ogive with leveling speed)
This operating mode is recommended
• for all conventional control with levelling switches.
• if control run-times lead to large tolerances.
• if strong slip develops on the leading sheave.
• if speed signal are noisy.
• if the shaft signals are not accurately installed.
• if mechanical transient processes must be waited for.
The procedure is active as long as a crawl speed entered in LF.21 is larger than 0 m/s.
V Speed
VN Nominal speed
vL Levelling speed LF.21
P1 Deceleration point from rated speed VN to
crawl speed VL
P2 Levelling switch
s1 The distance between deceleration point
and levelling switch is measured.
s2 Levelling path + stopping path
Following conditions must be created:
• Adjust/install deceleration points on all floors and for both directions equally.
• Distance of the deceleration points as far away as possible from the floor, so that a pleasant ogive rounding is
possible.
Distintive features of ogive run with crawl path:
• The F5-lift optimizes the crawl path principally to 5 cm.
• This also applies to the run with rated speed.
• ADA-function (auto deceleration adaption): If the change-over from VN to VL takes place too late at higher
floors, the F5-lift calculates a driving curve with steeper deceleration in order not to overrun the stopping positi-
on.
Start-up:
• Check whether Lb.4 = 1 is adjusted (Factory setting)
• Enter deceleration path in LP.3
• In case of unknown distances (e.g.renovation) carry out a calibration run, for that adjust LP.1 = 1 and perform a
normal drive. The distance between deceleration point and levelling switch is measured.
• For a checkup compare input value with the calculated deceleration path in LP.2. Here the required minimum
deceleration path is displayed (see mapping: Distance „s3" + 5 cm). The value in LP.3 always must be larger or
equal to the value in LP.2.
• If the deceleration curve is subsequently adjusted „softer", check again whether value LP.2 is smaller than value
LP.3.
• Swith LP.1 to 2. Thereby the value from LP.3 is accepted and the ogive function is activated.
Trouble-shooting:
• If LP.2 is larger than LP.3, increase the deceleration distance and correction in LP.3 or adjust a „harder" decele-
ration curve.
• If the lift overruns the floor, an error in the measuring system of your shaft encoding exists.
• If the crawl path of 5 cm should be too short, enter a smaller value in LP.3. Reduce LP.3 by as many cm as the
crawl path shall become longer.
