Force limit for learn run

Description of function
Maximum force that is active during the learn run. The force limit is active in the closing and
opening direction.
The maximum value of the parameter depends on the existing output transmission and the
maximum permissible output force of the motor gearbox. In the basic setting, the force limit is
set to the maximum value for the default output transmission of 176 mm/rev.
Note
The maximum force limit preset as a default for the learn run should be reduced for smooth-
running door systems or door systems with smooth end stops. A smooth-running door system
has a mass to be moved <100 kg and maximum frictional forces of <20N. If the force limit is set
too small for the learn run, the learn run aborts with the display code 'P'. If it is set too high, a door
width that is too large can be determined for smooth end stops or low belt tension. This results
in the initial operation not being left after switching on the supply voltage (the display code
remains at 'd' and does not change to 'u').
Connection and parameter assignment
The force limit can be configured via the terminal module (Main menu > General setup > Special
parameters > Force limit for learn run).
SIDOOR ATD420W / ATD430W
The force limit is set via the parameter p1242. See section Calibration and function parameters
(Page 192) for more on this.
4.1.3

Output transmission

Description of function
The output transmission must be configured for the M3, MDG3, M4, MDG4, M5 and MDG5
motors. The output transmission describes the transformation of rotational into translational
motion. Therefore: The distance [mm] that the door travels with one revolution [rev] of the
transmission output shaft. The output transmission can be adjusted within the range 0...384
mm/rev. The permitted values are between 88...384 mm/rev. The default value for a newly
trained motor type is 0 mm/rev.
