Parameter Object
(Class ID 0F
H
)
The DeviceNet Parameter Object provides the interface to the
Ultra3000 Drive with DeviceNet configuration data. It supplies a full
description of the parameter, including its minimum and maximum
values and a readable text string describing the parameter. The
instances start at one and increment with no gaps.
The table Parameter Instance on page 2-47 lists the parameter
instances implemented in the Ultra3000 Drive with DeviceNet. The
table Parameter Object Instance Attributes on page 2-97 lists the
instance attributes of the parameter object. A parameter value is
accessed via Attribute 1 of a parameter instance. Additional
information about the parameter object is located beginning on
Page 2-99.
