Mass determination
WARNING
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:
m
rms
= m
door
+ m
rot
+ m
mech
m
rms
: Mass to be moved
m
door
: Door mass
m
rot
: Mass equivalent of the rotor inertia of the motor
m
mech
: Moved mass of the door mechanism
No general information can be provided here for the mass of the door (m
door
) and the moving
mass of the door mechanism (m
mech
). These values are determined for the specific door
system.
The mass equivalent of the motor's rotor inertia (m
rot
) depends on the motor type, the drive
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:
Motor
Mass equivalent (mrot)
M3 and MDG180
22 kg
M4 and MDG400
22 kg
M5
93 kg
