63645 CC_ROCO_AX_TORSION_STIFF
Torsional stiffness of the drive train in [Nm/rad]
Description:
Torsional stiffness of the axis. Quantity at the output in [Nm/rad]
The initial value should correspond to that of the gearbox. A more precise determination can be made with AST.
The MD is created as field. If a value >0 is only entered in the index, the torsional stiffness is constant in all positions and at
all working points.
Indices 1+2 define a dependency on the axis holding torque.
k_(tor,wirk) = max(k_tor [0],k_tor [2]*|F_Mot | + k_tor [1])

63646 CC_ROCO_MOT_INERTIA
INERTIA Motor-related moment of inertia in [kgm2]
Description:
Motor-related moment of inertia. The inertia installed close to the motor (motor-related moment of inertia) that does not
change with respect to the position should be entered in this parameter. Output side quantity in [kg.m2]
