Motor data object, class 28h
The Motor data object can only be used if the ODVA AC/DC drive
profile is in use.
The object serves as a database for motor parameters. Different
motor types require different data to describe the motor. For
example, AC induction motors do not need field current data like a
DC motor to describe the motor.
