WARNING
The position function block is not a safe function and must not be used in the context of an area
where injuries can occur. To ensure safe use, the appropriate guards must be used by the user.
WARNING
Danger of injury and material damage when determining position
Position determination, as described in the relevant chapters and generally available, is not
guaranteed with a view to safe travel without endangering man or machine. All available and
determined position data of the SIDOOR control unit must be regarded as a guideline with an
equivalent inaccuracy, which is strongly dependent on the overall structure of the door and the
associated mechanical components. In addition, when changing speed, the distances for
acceleration, braking distances and controller deceleration must also be taken into account.
The precision and reliability of the position determination must therefore be determined anew
for each application as a whole.
According to the technical options, a maximum deviation between the determined position in
the control unit and the actual position of the door of up to +/- 2 cm can occur during position
detection.
Example calculation for the determination of the driving accuracy: When using accessories
o󹪜ered by Siemens (toothed belts, pulleys, etc.), a maximum position variance of +/-1 cm can
be expected for an e󹪜ective force of 300 N over an e󹪜ective length of 4 m. The condition for this
example calculation is a properly tensioned toothed belt, which means that any skipping of the
toothed belt can also be ruled out.
