operation. When this is the case, the test process is automatically terminated and a
test error is reported that is stored in the Hookup Test Status output parameter.

Get/GSV REAL - - - Electrical Degrees
The Hookup Test Commutation Offset reports the measured commutations
offset of a PM motor during the Commutation Test. This represents the value
that will be applied to the motor position accumulator in order to align the
Electrical Angle signal with motor stator windings. This value can be used to
configure the Commutation Offset attribute.

0 = Normal
1 = Inverted

The Hookup Test Commutation Polarity reports if the UVW phasing of the
Encoder or Hall Sensor match the phasing of the Motor. If the motor and UVW
commutation phasing do not match the Commutation Polarity is Normal. If it is
determined that the phasing for the motor and commutation device do not match,
this parameter reports that the Commutation Polarity is Inverted. This value can
be used to configure the Commutation Polarity attribute.

0 = Positive
1 = Negative
2...255 = Reserved
The Hookup Test Feedback 1 Direction attribute reports the direction of axis
travel during the last hookup test as seen by the drive's feedback 1 device. A value
of 0 (positive) indicates that the direction of motion as observed by the drive's
feedback 1 device was positive, for example, increasing counts. Note that the value
for Hookup Test Feedback 1 Direction, as determined by the hookup test, does
not depend on the current feedback, motor, or motion polarity attribute
configuration. This value, combined with the user's definition of forward
