Siemens SIDOOR ATD4 W Series - Obstruction Detection

Activation
Positioning mode can only be activated from normal mode and at standstill via the "positioning"
door command. It can be modi󹪝ed by the "NDG" and "slow" door command extensions. The
target position is transferred as the DESTPOS signal (see DESTPOS signal (Page 320)) in
technology control word 2 (TSW2) of the process image. The target position is automatically
limited to the learned door boundaries.
Sensors
Sensor signals are evaluated in positioning mode. You can 󹪝nd the reaction of the control/drive
unit to the corresponding sensor signals in the section ESPE (Page 114) or Pressure sensitive
edge (SR) (Page 115).
Motor protection
To protect the motor, a monitoring function is active that switches o󹪜 (deenergizes) the drive if
the speci󹪝ed target position cannot be reached, e.g. due to an obstruction.
4.3.8 Obstruction detection
Description of function
SIDOOR ATD401W
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.
Note
Obstruction detection
The factory-set obstruction detection response of the ATD420W and ATD430W controllers
corresponds to that of the SIDOOR ATD401W controller.
The factory-set obstruction behavior of the SIDOOR ATD420W and ATD430W controllers can be
parameterized.
The factory-set obstruction behavior of the SIDOOR ATD401W controller is not parameterizable.
A detected obstruction is signaled by the DBLOCK (see DBLOCK signal (Page 323)).
