Hookup Test Result Attributes
These are the attributes that are associated with hookup result status applied to a Motion Control Axis
Hookup Test Status
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - All | Get/GSV | USINT | - | - | - | Enumeration 0 = Test Process Successful 1 = Test in Progress 2 = Test Process Aborted 3 = Test Process Timed-out 4 = Test Process Faulted 5 = Test Failed - no feedback 1 counts 6 = Test Failed - no feedback 2 counts 7...127 = Reserved 128 = Test prohibited - Axis Test Mode active 129 - 255 = Vendor specific |
The Hookup Test Status attribute returns status of the last Run Hookup Test service on the targeted drive axis. The Hookup Test Status attribute can be used to determine when the hookup test service has successfully completed. Conditions may occur, however, that make it impossible for the drive to properly perform the 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. Values in the normal vendor specific range (129-255) correspond to values defined in the vendor specific range in the open service on the device.
Hookup Test Commutation Offset
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - E PM | 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.
Hookup Test Commutation Polarity
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - E PM | Get/GSV | USINT | - | - | - | Enumeration 0 = Normal 1 = Inverted 2...255 = Reserved |
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.
Hookup Test Feedback 1 Direction
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - E | Get/GSV | USINT | - | - | - | Enumeration 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 direction, can be used to configure the various polarity attributes for the correct directional sense.
Hookup Test Feedback 2 Direction
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - E | Get/GSV | USINT | - | - | - | Enumeration 0 = Positive 1 = Negative 2...255 = Reserved |
The Hookup Test Feedback 2 Direction attribute reports the direction of axis travel during the last hookup test as seen by the drive's feedback 2 device. A value of 0 (positive) indicates that the direction of motion as observed by the drive's feedback 2 device was positive, for example, increasing counts. Note that the value for Hookup Test Feedback 2 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 direction, can be used to configure the various polarity attributes for the correct directional sense.
