HEIDENHAIN PWM 20 - Manual (Page 116)

November 2014 Software description 117
Many edges in the diagram indicate that not all positions were captured yet. Continue to traverse
the measuring range until no more edges are visible.
All positions have been captured (straight line at level 1).
The maximum deviation difference is within the tolerance (green symbol), and the monitoring
function therefore does not display any error (green symbol).
8 Press this key to exit the Comparison of position values 1 and 2.
If an error message is generated or if the deviation difference is >1, the encoder
is defective. Repeat the test in this case.
Note
You may reset the error message now; the wizard will remember it and add it to the result
screen.
