Instance Attributes
For instance 1, a Value of 1 means that the startup period is active. For
instance 2, a Value of 1 means that the machine is rotating in the reverse
direction.

Parameter Object
(Class ID 0F
H
)
The Parameter Object provides the interface to the XM-220 configuration
data.
Parameter Object instance 1 is for the Speed Mode setting (dual channel, single
channel redundant, or reverse rotation). Parameter Object instances 2 to 13
provide an alternate method of setting the configuration parameters with
EPATH data types. And Parameter Object instances 14 and 15 provide an
alternate method of setting the Produced Connection Size and Produced
Connection Path attributes for the Poll Connection because these attributes
can be difficult to get/set directly through the Connection Object.
