Leveling accuracy adjustment method
No crawling
or crawling
for too long
The system requires the elevator to firstly enter the crawling state after Dec. This is the basic
condition for ensuring the elevator leveling. If there is no crawling, the Dec. curve is too slow or the
elevator main board creep speed point is too short.
Debugging method:
• The curve is too slow, increase the value of F03.03, F03.04, F03.05.
• The elevator main board crawling Dec. point position is too short, increase the distance of the
elevator control board crawling speed over-change point, that is, the value.
•
If the crawling time is too long, the Dec. curve is too fast. At this time, the Dec. curve should be
adjusted so that it is crawling, but not too long, and the values of F03.03, F03.04, F03.05 are
reduced.
Low up,
down high
or up high,
low down
When the parking is low, the downward trend is high, indicating that the crawling speed is low;
When the parking is high, the downward trend is high, indicating that the crawling speed is high.
At this time, the crawling speed should be adjusted.
Low up,
low down or
high up,
down high
When the parking occurs, the uplink is low, the downlink is low or the upstream is high, and the
downward is high, indicating that the position of the door panel is biased.
At this time, the position of the door panel should be adjusted.
The
installation
position of
the upper
and lower
stations is
incorrect
Incorrect installation position of the upper and lower stations will affect the leveling accuracy of the
elevator at both ends. For the above end station as an example, the adjustment steps of the end
station position are as follows:
•
Install the end station switch at a position greater than the speed change distance;
•
The elevator runs quickly to the end station, and the uneven layer will appear after stopping the
speed change;
• Immediately set the system to an inspection state;
• Measure the distance of the elevator from the leveling layer, which is the distance that the upper
station needs to adjust upwards.
Similarly, the adjustment of the lower station can be performed.
Flat-level
fine-tuning
After the basic leveling is achieved by the curve parameter of the F03 group, the leveling accuracy is
adjusted by adjusting F03.13 (Stop Dec. jerk) when the crawling speed is normal. When leveling the
layer, increase the value of F03.13, the level of the leveling When, reduce the value of F03.13.
