CIP Axis Attributes

Device-to-Controller connection at power-up is zero. This is an indication to the
controller that the drive has been power-cycled and the drive axis needs to be
homed to establish a machine reference position.
When configured for Absolute mode, the device initializes the feedback count
accumulator at power-up to the absolute feedback position value read from the
feedback device. When the feedback device's absolute position range is less than
the 32-bit signed integer representation of the feedback count accumulator, the
absolute position is sign extended to a 32-bit signed value. While there are many
Feedback Types that support Absolute startup, there are a few strictly incremental
types that do not: Digital AqB, and Sine/Cosine.
Some device vendors tie the Feedback Startup Method to the Feedback Type
selection. In these cases, an attempt by the controller to incorrectly configure the
Feedback Startup Method will generate a General Status error of Invalid Attribute
Value.
The default Feedback Startup Method value depends on the associated Feedback
Type according to the following table:
