6.2.2 Door Width Self-learning

The door width of door motor is the basis for controlling the distance of the door motor, adjusting the

OD/CD running curve and judging complete OD/CD. The accurate acquisition of the door width is the

prerequisite for the normal realization of the distance control.

Note:

1. During the door width self-learning process, the direction of the door action will automatically change, so

please ensure personal safety before operating, otherwise it may cause personal injury.

2. Before door width self-learning, please make sure that there are no obstacles during the operation of the

door. If there are obstacles, the door width cannot be measured correctly.

Setting Door Width Self-learning

1. Set F00.02 = 1 (distance control), F00.03 = 0 (keypad control).

2. Choose self-learning method.

• Without a hall door: Set F02.05 = 1 (door width self-learning is valid).

• Press (RUN key) or (JOG key) to start self-learning. After completion, check F02.05 = 0.

• The door width data is recorded in F02. 06 and F02.07.

• With a hall door: Set F02.05 = 2 (door width self-learning is valid), the door vane distance can be learned.

• Press (RUN key) or (JOG key) to start self-learning. After completion, check F02.05 = 0,

F10.04 ≠ 0.

• The door width data is recorded in F02.06 and F02.07, and the door vane data is recorded in F10.04.

When an abnormality occurs during the door width self-learning process, press (STOP key) to stop.

Then press (RUN key (or JOG key) restart the self-learning.

The normal operation of self-learning is as the figue below.

Exception handling:

1. Giving door width self-learning command, the first running direction is CD.

Countermeasure: Stop MONT20 and exchange any two phases of U, V, W.

2. Check the CD pulse signal in self-learning. The CD pulse number increases if the OD pulse number decreases.

Countermeasure: Modify the setting value of F02.01 (encoder direction).

3. During self-learning, alarms E0026 fault (door width self-learning failed).

Countermeasure: Check encoder signal. For heavy load type, increase F05.14 (OD/CD switching torque).

4. When the Asyn. motor is self-learning, the door motor jitters and stops.

Possible reason: F02.00 (encoder pulse number), F02.01 (encoder direction), and F01.05 (deduction rate)

setting error.
