Learning in new motors (ATD4xxW)
The learned motor type is stored in the controller and compared with the connected motor
when the controller is switched on. The controller's operating status display shows the status
code "5" if the learned motor type differs from the connected one. A new learn run (when the
line voltage is applied) or a special learn run is needed to learn in the new motor type.
SIDOOR ATD4xxW controllers enable learning of a new motor type by means of a special
learn run, which can be started as follows:
● DCMD "Start learn run" (see Table 6-74 DCMD signal (Page 206)) and DCMD "special"
expansion bit (see Table 6-75 DCMD expansion bits (Page 207))
● In the service terminal via
Note
If a learn run is started with a new motor and if the learned motor type differs from the
connected one, for safety reasons the energy limiting parameters (p1202, p1203 and p1204)
and internal friction compensation are reset for all driving parameters.
For the M4, MDG400. MDG400 NMS and M5 motors, the output transmission [mm/rev] must
be configured. For the M4, MDG400 and M5 motors, set the default value to 176 mm/rev.*
The learn run does not start when a value is set outside the permitted value range for the
output transmission (for example, default value: 0).

Starting a learn run via the learn run button
You can start a learn run via the learn run button (S401/S1*). Proceed as described in
Section Service buttons (Page 110).
* SIDOOR ATE250S
Interrupting the learn run (SIDOOR ATD4xxW, ATE250S)
Users can interrupt the learn run. The system signals an interrupted learn run through the
door fault status and by changing to a special mode. The operating status display shows the
warning "_". See Section Operating state display (Page 183).
The following actions interrupt an active learn run:
● Repeated operation of the learn run button (S401/S1*)
● Operating the OPEN or CLOSE service buttons (S402/S2* or S403/S3*)
● Door command change (except "deenergized") via the terminal, the service interface or
the fieldbus system**
● Interruption of the ESPE or the pressure-sensitive edge**
