Siemens SIDOOR AT40 System Manual page 47

The DOOR OPEN command has priority over all other control commands.
Note
If the commands DOOR CLOSE and DOOR OPEN are present simultaneously, the door moves in
the OPEN direction.
As of version AT40 V1.47 and ATD400V V1.08, the idle torque in the end position can also be
activated without an active door command by using the service menu "General setup -> Special
parameters -> Idle torque without door command". The default value for this parameter is "OFF"
(no idle torque without door command). The following function is active when the set value is
"ON":
• In the OPEN position, the door is kept open with set torque, even if no active Door OPEN
command is pending. If in this case the door is pulled out more than 20 mm from the OPEN
position, no new travel into the OPEN position takes place. Relay X13 (OPEN position
detected) becomes active when the door control unit has detected the door end stop.
Note
The idle torque has to be set so that the door cannot be pulled from the end position, e.g.
through the counterweight or rubber buffers in the end stop. See also the sections "Forces
(Page 94)" and "Oscillation protection (Page 48)"
As of version AT40 V1.47 and ATD400V V1.08 the creep speed can be reduced to 3 cm/s when
2 cm in front of the end position OPEN, using the service menu "General setup -> Special
parameters -> Slow travel to OPEN end position", irrespective of the parameterized value. The
default value for this parameter is "OFF" (no change of the slow end speed). The following
function will become active when the set value is "ON":
• During the last 2 cm of the opening travel, the door is decelerated to 3 cm/s. The kinetic
energy is reduced when the open position is reached.
The reversal behavior in opening direction is described in the section Obstruction detection
OPEN (Page 54).
As standard, no command output via the digital inputs is possible with an activated CAN
interface.
As of version AT40 V1.49 and ATD400V V1.10, a DOOR OPEN command can be output via the
digital input signal DOOR OPEN, also with activated CAN interface. This command has a higher
priority than the door commands via the CAN interface. This function can be activated using the
service menu "General setup -> Special parameters -> OpenCAN inp." For compatibility reasons,
this function is deactivated by default.
Connection
The "DOOR OPEN" function is connected to the input terminal X6 Pin 1. See also section Digital
input signals (Page 68).
