This floating point value represents the active load offset measured during the last
successful Inertia Test profile. This value can be used to set the Torque Offset of
the drive to cancel out the active load torque/force. This value may also be set
directly by software tuning tools or programmatically.

Load Inertia / Motor Inertia
This floating point value represents the load ratio calculated by MRAT based on
the measurements made during the last successful Inertia Test profile. The Load
Inertia Ratio attribute's value represents the ratio of the load inertia to the motor
inertia. Or in the case of a linear motor, the load mass over the motor mass. This
value can be used to set the Load Ratio attribute value as part of an Autotune
process. This value may also be set directly by software tuning tools or
programmatically.
