The machine tool door drive is comprised of a controller and a maintenance-free drive unit (geared motors).

Controllers are electronic controllers connected to the power supply via an external power supply unit (SIDOOR NT40, SIDOOR Transformer). They are generally connected to the higher-level controller via digital or fieldbus interfaces, and can be configured via a user interface.

Various controllers for doors weighing up to 600 kg (1323 lb) are available for machine tool doors.
