General Feedback Info Attributes
These are the general feedback information attributes associated with a Motion Control Axis.
Feedback n Serial Number
Usage | Access | Data Type | Default | Min | Max | Semantics of Values |
---|---|---|---|---|---|---|
Optional - E | Get | SHORT STRING | - | - | - | For example, 0012003400560078 |
The Feedback n Serial Number attribute is a 16-character string that specifies the serial number of the device associated with Feedback n. If it is not possible for the drive to read the Serial Number from the feedback device the drive sets this attribute to a Null string.
For track systems, the Feedback 1 Serial Number attribute returns the physical mover sequence number assigned to the mover axis by the track system’s mover-axis assignment process. The controller can use this unique value the to verify that the mover-axis assignment has not changed as part of the APR process. If the mover axis instance cannot be assigned to a physical mover, the track section sets this attribute to the Null string, 0.
Position Feedback n
Usage | Access | Data Type | Default | Min | Max | Semantics of Values |
---|---|---|---|---|---|---|
Require - E | Get/GSV | DINT | - | - | - | Feedback n Counts |
The Position Feedback n attribute is the actual position of the axis based on Feedback n.
