SIDOOR ATD4xxW obstruction detection

Description of function
SIDOOR ATD401W (SIDOOR ATD4xxW factory default, firmware version 1.03 or higher)
If the controller detects an obstruction in the opening or closing direction with the aid of
obstruction detection, it reverses once by 20 cm, starts an attempt to retract and then
switches to wait mode. Slow obstruction approach, force obstruction detection and stop
obstruction detection are active.
SIDOOR ATD410W/ATD420W/ATD430W (up to firmware version 1.03)
● If the controller detects an obstruction in the opening direction by means of obstruction
detection, three retries are initiated, each offset by 2 s.
● If the controller detects an obstruction in the closing direction by means of obstruction
detection, it reverses by 20 cm and starts an attempt to retract. This operation is repeated
twice and is offset by 2 s in each case.
The controller then switches to wait mode. Slow obstruction approach, force obstruction
detection and stop obstruction detection are active in both cases.
Note
SIDOOR ATD4xxW obstruction detection (firmware version 1.03 or higher)
The behavior of the obstruction detection of ATD4xxW controllers corresponds to that of the
SIDOOR ATD401W controller.
The factory-set obstruction behavior of SIDOOR ATD410W, ATD420W and ATD430W
controllers is parameterizable.
The factory-set obstruction behavior of the SIDOOR ATD401W controller is not
parameterizable.
A detected obstruction is signaled by the DBLOCK signal (see Table 6-83 DBLOCK signal
(Page 211)).
The subsequent response to a detected obstruction depends on the user-defined parameter
assignment. The following properties can be configured separately for the opening and
closing directions:
● Obstruction detection
● Direct response
● Behavior following an obstruction
Basically, the same parameters are available for both drive directions. This means that either
the same or different obstruction behavior can be configured for each direction.
The obstruction detection is a dynamic system that responds as a function of both position
and time. The obstruction detection is dynamically activated or deactivated according to
these dependencies. You will find more detailed information in Section Expert configuration
(Page 64).
