1.
Travel from both sides to all floors using command V3 normal travel, displace the stop switches in a way that the
car may stop flush.
HINT:
If the
positioning travel is too short
, or
a jerking can be noticed in the car at the correction point
, the measured
braking distances are shorter than the parameterized Brak.dist.3 (that means, the speed at the correction point
stop switch is too high). The measured braking distance is shown in the display with
Brak.d.(S) = xxx.xx
cm.
REMEDY:
-
First of all increase the positioning distance Position. in
P-TRAVEL CURVE DATA
. If this action carries
no advance, see
Checking the braking distances
The
measured
braking distance is computed via counting the pulses regarding the system data (e.g. v/n-value).
Operating without pulse generator (actual value) the value is determined via the integration of the rated value
curve. According to the deviation from the actual rated value this method results in other values for the indicated
Brak.d.(S)
.
The actual (measured) braking distance should correspond centimeter exact to the parameterized braking
distance (
P-TRAVEL CURVE DATA: Brak.dist.3
).
The measured braking distance
Brak.d.(S)
must in any case
not be shorter than the physical required minimum
braking distance from speed
v3
!
•
Check the calculation of v/n from section

, page

, item

!
•
Adjust the braking tags in the shaft if the values for the measured braking distance
Brak.d.(S)
and the
parameterized distance
Brak.dist.3
differ.
−
If the differences are small (below 2 cm!) it is sufficient if travel curve with positioning has been selected to
parameterize the
smallest measured braking distance (S
)
in P-TRAVEL CURVE DATA: Brak.dist.3
!
Checking the correction point stop switch
The correction point
stop switch
should be located in the range of the constant positioning (see
Figure 3: Braking distances
and travel curve designations)!
•
do the normal travel using
v3
•
select menu item speed at the stop switch
Speed (A)
in the menu
P-DRIVE DATA
−
the indicated value should correspond to the traveled positioning speed
v Posi
(display: v-travel:=x.xx m/s), in
order to get the correcting access no to be remarked in the car (The positioning speed is automatically
lengthened or shortened).
If the displayed value is higher than the positioning speed traveled at the moment: increase the positioning
distance (
P-TRAVEL CURVE DATA: Position.
)!
2.
If the
positioning travel takes too much time
increase the
Brak.dist.3
in
P-TRAVEL CURVE DATA
, to reach shorter
positioning times.
Commissioning for rated speed
v 3
has been finished. For possibly having intermediate speeds
v 1
or
v 2
the suitable
braking distances have to be parameterized.
