The Converter Capacity attribute is the real-time estimate of the continuous rated
converter thermal capacity utilized during operation based on the converter
thermal model. A value of 100% would indicate that the converter is being used at
100% of rated capacity as determined by the continuous current rating of the
converter. If the CIP Motion device applies I
2
T overload protection rather than
thermal model based overload protection, the Converter Capacity value is zero
until the converter current exceeds its factory set overload current rating. Once in
an overload condition the Converter Capacity increases from 0 according to the
I
2
T calculation. A value of 100% in this case indicates that the converter has used
up 100% of its I
2
T overload capacity.
The converter overload protection method applied by the device is indicated by
the Converter Overload Protection Method attribute.

The Bus Regulator Capacity attribute is the real-time estimate of the continuous
rated bus regulator thermal capacity utilized during operation based on the bus
regulator thermal model. A value of 100% would indicate that the bus regulator is
being used at 100% of rated capacity as determined by the continuous current
rating of the bus regulator.
If the CIP Motion device applies I
2
T overload protection rather than thermal
model based overload protection, the Bus Regulator Capacity value is zero until
the bus regulator current exceeds its factory set overload current rating. Once in an
overload condition the Bus Regulator Capacity increases from 0 according to the
I
2
T calculation. A value of 100% in this case indicates that the bus regulator has
used up 100% of its I
2
T overload capacity.
The bus regulator overload protection method applied by the device is indicated
by the Bus Regulator Overload Protection Method attribute.

The attribute tables contain attributes associated with auto-tuning and test
services applied to a Motion Control Axis Object instance. These attributes are
unique to the controller and do not require replication in the Motion Control
Device Axis Object.
