Siemens SIDOOR ATD4 W Series - Overload Protection of the Geared Motor; Vandalism Protection;Continuous Door Monitoring

Using an end position sensor
You can skip initial mode by connecting a DCOPS end position sensor (Door Closed/Opened
Position Sensor). Depending on the application, 1 end position sensor can be used in the open
or closed position or 2 end position sensors can be used in both end positions. The responsibility
for veri󹪝cation of the learned end positions is thus transferred to the user (see section DCOPS
(door closed/opened position sensor) (Page 67)).
4.2.2 Overload protection of the geared motor
Function description
The overload protection should prevent a thermal overload of the motor. While the overload
protection is active, the 7-segment display (H401) shows the fault code "4". The overload
protection is activated by the cases listed below:
• If the geared motor placed under a high load with frequent OPEN DOOR and CLOSE DOOR
commands in quick succession, the hold-open time is automatically lengthened. The next
closing movement is delayed even if a DOOR CLOSE command is present.
An extension of the hold-open time may occur if the dwell time of the door in both end
positions together, per drive cycle, is less than 12 seconds on average.
• If the drive is operated continuously for more than 65 seconds in one direction, fault "4" is
displayed and the motor stops. After acknowledgment of the fault a restart of the control unit
takes place. This can occur only with extremely high system friction, low door speeds and
large door widths.
• If the door is blocked longer than 5 seconds outside the obstruction detection area (p3856,
p3857, p3873, p3874), the motor current is reduced to the nominal motor current. If a
motion of the door in the drive direction is detected, the motor current is increased in
accordance with the parameterized force limit and fault "4" is terminated.
4.2.3 Vandalism protection/continuous door monitoring
Description of function
The vandalism protection/continuous door monitoring function o󹪜ers protection against
undesired external system motion. If the motor is deenergized, the motor speed is monitored by
the controller.
If the maximum speed of 250 mm/s is exceeded, the controller actively decelerates the motor to
50 mm/s, and then switches the drive back to "deenergize".
As of V1.10: With the M5 and MDG5 motors, the maximum speed at which vandalism protection
is applied is 200 mm/s.
SIDOOR ATD420W / ATD430W
If the maximum con󹪝gurable speed (p1200) is exceeded, the controller actively decelerates the
motor to 50 mm/s, and then switches the drive back to "deenergize".
