6.3 Distance Control Parameters
In distance control mode, based on the door width acquired from
auto-learning, in CD/OD process, the pulse is counted in real time, which is
compared with the preset pulse to change speed during CD or OD. The
control process is shown in Figure 6-8.
Distance control includes distance control 1 and distance control 2, and their
control logics and operating curve are exactly the same. In distance control 1,
the PG information is used both in control and pulse counting, and under this
condition, the PG must be connected to the shaft of the motor. In distance
control 2, the PG information is only used in pulse counting, and under this
condition, the PG needs not to be connected to the shaft of the motor.

In distance control, besides F010 ~F040, the parameters F044~F052 also
needs to be set.
Door width auto-learning should be implemented before distance control. The
speed curves of distance control are illustrated by Figure 6-9 and Figure
6-10.
