3.1 Basic functions
Mass determination
Door weight determined with the learn run
Depending on the mechanical coupling between the motor and door panel, the door weight
determined during the learn run can differ from the actual door weight. For the motors M5
and MDG700NMS, the maximum possible mass is always preset for the learn run. The
door weight determined during the learn run has to be checked and if necessary corrected
using the basic parameters editor (from V1.10).
The moving mass (effective mass) of all the moving elements of the motor, the door
mechanism and the door is determined with the learn run.
The mass to be moved is calculated from the sum of the mass equivalent of motor's rotor
inertia, the moving door mass and the moving mass of the door mechanism:

The mass equivalent of the motor's rotor inertia (m
ratio at the motor shaft and the transmission efficiency.
The following tables list the mass equivalent of the rotor inertia for SIDOOR motors with a
transmission efficiency of 85%.
For the motors SIDOOR M3, M4, M5, MDG180, MDG400, the mass equivalent of the rotor
inertia of the motor is constant:
