The SIDOOR ATD401W machine tool door drive is an intelligent door control system that enables protective doors on machine tools to be opened and closed at adjustable speeds and accelerations.

They must be ordered separately, see "Geared motors".

Operation of the door drive does not require limit switches. The door width and the "OPEN"/"CLOSE" positions are determined automatically.

The current operating states are shown on a 7-segment display directly in the SIDOOR ATD401W machine tool door drive. They can also be displayed externally using the Software Kit or Service Tool, see "Additional units".

Forces are transferred via a toothed belt which passes over a deflector unit and can be fitted with two door clutch holders. The accessories are not included in the scope of delivery, see "Accessories".

This enables handling of both single leaf and centrally opening doors.
