The Rotary Motor Inertia attribute is a floating point value that specifies the
unloaded inertia of a rotary motor.

RPM
The Rotary Motor Rated Speed attribute is a floating point value that specifies the
nameplate rated speed of a rotary motor. For PM motors, this is generally specified
at rated voltage based on either rated current, rated torque, or rated power. For
induction motors this value is the speed of the motor driven at rated frequency
under rated torque load. This value is synonymous with the term base speed.

RPM
The Rotary Motor Max Speed attribute is a floating point value that specifies the
absolute maximum operating speed of a rotary motor in units of RPM. This speed
may be determined by the limitations of the motor, limitations of the drive power
structure, or by limitations of the mechanical system, whichever is less. Specifically,
this value can represent the maximum safe operating speed, maximum continuous
no-load speed, maximum encoder speed, maximum continuous motor bearing
speed, or maximum motor speed based on the drive power structure voltage limit.
This value can be used by the drive to determine the Rotary Motor Overspeed
Factory Limit.

The Rotary Motor Damping Coefficient attribute is a floating point value that
specifies the damping, or viscous friction, associated with a rotary motor.
