4.2 Dimensioning gear units
Acceleration and deceleration values
To secure that gear units will not run too hard and damage the gear box, the
acceleration and deceleration of the axis on the arm side must be calculated.
This calculation will give a maximum value for the system parameters Nominal
Acceleration and Nominal Deceleration . The value can be lowered if the acceleration
is too fast, see Application manual - Additional axes and stand alone controller .
Do not use values higher than the recommended maximum acceleration, see
Maximum gearbox torques on page 71 .

is the moment of inertia around the Z axis at the center of gravity (CoG).
CoG

is the radial distance in X and Y directions between the Z axis and the
center of gravity (CoG).
Define the system parameters Nominal Acceleration and Nominal Deceleration in
the type Acceleration Data in the topic Motion , based on the calculations.
