Parameter Description
Ogive run with direct approach (DODA = digital ogive with direct approach)
This operating mode is recommended
• if the change-over of the speed inputs takes place precisely and fast (ca. 1 ms)
• if the mentioned problems at ogive run with crawl path do not exist. Otherwise it result in non-levelling.
The procedure is activated by adjusting the crawl speed LF.21 to 0 m/s.
P1 Deceleration point from rated speed VN to crawl
speed VL
s Path of deceleration = LP.03
V Speed
t Time
Start-up:
• Check whether Lb.4 is adjusted to 1 (factory setting).
• Check whether LF.21 is = 0 m/s.
• Enter path of deceleration in LP.3. The path of deceleration in LP.3 must match the position of the decelerati-
on points in the shaft to the millimeter. It is measured from the deceleration point to the levelling position/door
threshold.
• Activate ogive run with LP.1=2.
Ogive run with direct approach and correction shortly before the stopping position (DODAC = digital ogi-
ve with direct approach and correction)
This operating mode is recommended
• if only minor system errors (up to 3 cm) need to be adjusted.
With this procedure ca. 10...15 cm before the stopping position a digital input is set on the frequency inverter, by
which the actual residual distance is detected.

P2 Correction switch
s Path of correction = LP.04
V Speed
t Time
Start-up:
• Check whether Lb.4 is adjusted to 1 (factory setting).
• Check whether LF.21 is set to 0 m/s.
• Adjust Lb.10 to 2 (customer-specific input assignment)
• Adjust Lb.12 to 9 (assignment of correction input is terminal X2A.17)
• Enter path of deceleration in LP.3. It is measured from the deceleration point to the levelling position/door
threshold. The path of deceleration in LP.3 must match the position of the deceleration points in the shaft to the
millimeter.
• All correction points must have exactly the same distance (residual distance) to the stopping position.
• The path of correction (residual distance) must be entered accurately to the millimeter in LP.4.
• Activate ogive run with LP.1=2.
