SIDOOR AT40 BASIC, SIDOOR AT40 RELAY and SIDOOR AT40 CAN firmware update V1.46 to V1.47

FW update: V1.46 to V1.47

Scope and purpose:

This document provides an overview of the new functions and the release status of the firmware for the products SIDOOR AT40 BASIC, SIDOOR AT40 RELAY and SIDOOR AT40 CAN with firmware version V1.47.

This firmware contains important function extensions that make for easier operation in elevator systems and support service engineers in their work.


New functionality:


1. Activation of the holding torques in the end positions of the door without active drive command

The "Continuous torque without drive command" function can be set with a separately adjustable parameter.

  • Setting "No"        --> factory setting (not activated)

  • Setting "Yes"            --> When the door has reached the end position, the  continuous torque is activated.


This new function prevents an oscillation of the door in the end positions
when the drive command is canceled by the higher-level elevator control when the end position of the door has been reached.

Notice: The values of the continuous torques must be set so that the door can be held in the position against a counterweight or a spring force which press the door out of the end position.

2. Input 1 (light barrier / DCPS) can be deactivated in a third function


Notice: Thanks to the new function it is no longer necessary to install hardware jumpers when the light barrier is not needed. It can be simply deactivated in a menu.


  • Setting "LS"           --> factory setting (light barrier activated)

  • Setting "DCPS"      --> The "Door close position sensor" function is activated.

  • Setting "deactivated"           -->  Input 1 has no function and wiring with hardware jumpers to disconnect the light barrier is no

         longer necessary.


3. Readable checksum


The checksum is stored internally for unique identification of the firmware. For acceptance or certification of the elevator door control system, the inspector can read out the checksum with a menu command.



4. Automatic presetting for SIDOOR AT40 CAN


For controllers with internal CAN module, command output via CAN is the factory default setting.


Factory default setting:

    • Command output:                    CAN

    • Baud rate:                                automatic

    • Node ID:                                 7

    • Door number:                             1

    • CAN Condition Monitoring:      OFF

5. Slow travel to "OPEN" position

The creep speed can be reduced to 3 cm/s by a separately adjustable parameter about 1 to 2 cm before reaching the end position "OPEN".

This setting is independent of the set creep speed in the creep distance that can be set with 3-9 cm/s.

    • Setting "OFF"       -->  factory setting (not activated)

  • Setting "ON"          -->  The creep speed setting with 3 cm/s becomes active automatically about 1-2 cm

                                           before the "OPEN" end position so that the door

                                           travels into the end position slowly.



6. The light barrier reaction can now be configured.


The reaction to an interruption in closing direction of the door can now be parameterized for SIDOOR. A complete opening as well as "tracking mode" are possible as long as the light barrier is interrupted.


  • Setting "No"       -->  factory setting (tracking mode). The door opens as long as

                                           the light barrier is interrupted. 

  • Setting "Yes"           --> The door opens completely across the entire door path after interruption

         of a light barrier. The close command must

         remain pending.

Frequent reversal in case of short-term interruptions of the light barrier is prevented by the new function.



7. Door mode available via CANopen

 The door controller provides the door mode via CANopen with the help of MPDOs.
(Init mode, Normal mode, Learn run mode, Error).



8. Debounced learn run button


For a learn run to be started, the learn run button must be pressed for at least 500 ms.



Detailed descriptions of the new functions and of the CAN objects supported in SIDOOR are provided in the product-specific documentation at the following link:

  • SIDOOR AT40, ATD400V System Manual, edition 11/2018.


  • SIDOOR Controllers for elevator doors, Compact User Manual, Edition 11/2018, ATE46306667-AA

  • Manufacturer-specific CANopen objects, edition 11/2018,



The firmware update can only be used with the following door control systems:

  • SIDOOR AT40 BASIC           MLFB: 6FB1111-0AT11-3AT0

  • SIDOOR AT40 RELAY          MLFB: 6FB1111-0AT10-3AT2

  • SIDOOR AT40 CAN             MLFB: 6FB1111-1AT10-3AT3

The SIDOOR SOFTWARE KIT (6FB1105-0AT01-6SW0) is required for the download.
