The SIDOOR ATD410W 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.

The maintenance-free, variable speed drive unit comprises a DC motor with non-self-locking gearing.

Five different motors are available:

• SIDOOR MDG180 geared motor
  (30 V DC/4.0 A; motor for max. overall door leaf weight of 180 kg, degree of protection IP56)
• SIDOOR MDG400 geared motor
  (30 V DC/4.0 A; motor for max. overall door leaf weight of 400 kg, degree of protection IP56)
• SIDOOR M3 geared motor
  (30 V DC/4.0 A; motor for max. overall door leaf weight of 180 kg, degree of protection IP40)
• SIDOOR M4 geared motor
  (30 V DC/4.0 A; motor for max. overall door leaf weight of 400 kg, degree of protection IP40)
• SIDOOR M5 geared motor
  (30 V DC/7.5 A, motor for max. overall door leaf weight of 600 kg, degree of protection IP54)

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 indicated by a 7?segment display directly in the SIDOOR ATD410W machine tool door drive. They can also be displayed externally using the Software Kit or Service Tool, see "Additional units". The associated function block can be used for configuration and parameter assignment purposes, see "Programming".

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 supply, see "Accessories".

This enables handling of both one-sided and centrally opening doors.
