High improvement of high -level elevator learning function, high -rise elevator response plan

2024-05-29

1. High lifting height learning function of the elevator

Due to the stretching of the traction wire rope and the speed limit device wire rope, the

elevator may shake the car in the bottom floor and cause the accuracy error of the flat floor in the low area. To avoid the above two situations, the following two functions are used :

① Car vertical vibration suppression function (FF control)

② Speed limrope tension correction function (GRS correction)

In order to learn the parameters of each control function, the operations need to be learned.

[matters need attention]

When the mechanical properties of the wire rope change, the above learning homework needs to be done again.

For example, replace the wire rope. After the replacement is

completed, redo the above study homework and rewrite the

height. · The error of the bottom layer becomes larger (visual inspection ; above ± 5mm)

· After the wire rope replacement

· After wire

rope cutting · After secondary decoration of

the car

[Confirmation method]

To firm whether these functions work as follows.

① Ground floor area, elevator maintenance (manual) mode, SET 1 / 0=A6, SW 1 ▽ (long press) and SW 1 ▽ (long press)

If "F1" flashes, these functions are in a valid state. (This step describes the learning in 1-1)

② After the writing layer is completed, the elevator is in the bottom automatic mode, with SET 1 / 0=A / 9, SW 1 ▽ (long press) and SW ¹ ▽ (long press)

If the "GS" flashes, these functions are

in an active state. (This step describes how effective the learning content in 2- 1)

0. Jobs after rewriting to the software

0-1. Automatic layer height learning

After rewriting the software, there will be a layer picker fault. So you need to write the layer automatically.

1. Manually write pre-layer jobs

Note : Before completing the learning operation, if the CPU is cleared, the learning data will also be cleared. So you have to learn it from scratch.

2. After manually writing the layer of homework

2 - 1 . Scaling volume GRS, primary learning [SET 1 / 0=A / 9]

· If the elevator running speed cannot exceed 60m / min or the accuracy of the bottom layer needs to be improved, you can learn the expansion amount of the bottom speed limit rope through the initial operation of GRS.

· After the learning operation is completed, the elevator continues to run to the top floor. If the adjustment is completed, the elevator will stop sharply once in operation due to the # 29 OFF fault. · The learning operation should be carried out under half a load in the sedan car.

3. Work after adjusting the balance coefficient

After adjusting the balance coefficient, we can improve the learning accuracy.

3-1. Bottom layer high corrected learning [SET 1 / 0=A / D]

· The height correction of the elevator at the bottom layer and the bottom layer is obtained

by comparing and calculating the height value measured in 4m / min maintenance operation and the height value measured in the automatic writing layer mode.

· In order to improve the learning accuracy, please automatically write the layer during the half load in the car.

3 - 2 . Scale GRS learning operation (top, bottom) [SET 1 / 0=A / A]

· The top and bottom expansion GRS is learned through the elevator to the top floor at 90m / min and 240m / min.. After completing the bottom layer high correction learning, perform the learning operation.

19. Operation after learning failure

The reasons for learning failure are shown below, and then after again. · The

elevator stops on other floors (except for the target floor) · The elevator speed

curve is abnormal.

· Layer selector failure

· Expansion volume GRS corrected value over 200mm (please contact the Engineering

Headquarters). · The expansion capacity of the traction wire rope exceeds 200mm (please

contact the Engineering headquarters).

[matte r s n eed atte n tio n ]

1. In the learning operation, when the elevator reaches the target layer, if the elevator stops

outside the area of the leveling layer, it is necessary to make the elevator run to the leveling

layer area after the action or through the maintenance mode, and then confirm to enter the learning mode and conduct the next learning operation. (Show that [", not [4])

If the elevator does not stop in the re-level area (display ["] instead of [4]), the elevator will not be able to perform the next learning run.

4. Work during comfort adjustment

4-1. Manually adjust the expansion GRS, and the corrected value [SET 1 / 0=AC] · adjust the expansion GRS correction

value.

(If the bottom GRS correction value increases, the elevator bottom level level position will be insufficient; if the bottom GRS correction value decreases, the elevator bottom level position will be excessive)

① Confirm that the elevator is stopped.

② "SET 1 / SET 0 = A / C" is set on the P1 board, and sW 1 moves down into the mode.

③ Through SW 2 to change the "bot" display value on the digital tube, and SW 1 to dial down to confirm.

④ For example, adjust the display value to "b005" (5mm) or "b012" (12mm), SW 1 dial down to confirm. SW 1 moves up to change the target bit to be set (the decimal point under the

selected digital tube lights up)

SW 2 moves up and down, change the value by one bit, and SW 1 moves down to confirm the value (write to the parameter).

⑤ After the adjustment, set the "SET 1 / SETO = 0 / 8" exit adjustment mode.
