Gocator Line Profile Sensors: User Manual
Protocols • 395
Field Type Offset Description
0 – General failure
-1 – No data in the field of view for stationary alignment
-2 – No profiles with sufficient data for line fitting for travel
alignment
-3 – Invalid target detected. Examples include:
- Calibration disk diameter too small.
- Calibration disk touches both sides of the field of view.
- Too few valid data points after outlier rejection.
-4 – Target detected in an unexpected position.
-5 – No reference hole detected in bar alignment.
-6 – No change in encoder value during travel calibration
-988 – User aborted
-993 – Timed out
-997 – Invalid parameter
