Depending on the scaling type setting, there are the following predefined
preferred scalings:

Overview: preferred scalings for acceleration data and jerk data
Note:
The jerk data scaling is derived from the acceleration data
scaling.
The acceleration data can also be scaled with reference to a velocity

Definition of the velocity reference ramp for scaling acceleration data
in the case of preferred scaling
The scaling types, units and the selection of preferred scaling are
determined in the respective bits of the following parameters:
•
S-0-0076, Position data scaling type
•
S-0-0044, Velocity data scaling type
•
S-0-0160, Acceleration data scaling type
When using preferred scaling, the parameter values for scaling type, unit,
scaling factor and scaling exponent as well as the number of decimal
places are automatically set for the respective data. The following table
contains an overview.
