(c) Detection Waveforms
The Sigma Win+ trace function can be used to check whether detection is normal.
• Normal Detection
The detection result is normal if the speed feedback for the speed reference for the last detection waveform
(unspecified number of detections) is traced. The following criteria are used to determine whether a trace is
being performed.
• The feedback polarity is not inverse to the reference (speed is in same direction).
• The feedback speed range is 2 mm/s up to the maximum reference speed.
• Detection Error
The detection result is an error if the speed feedback for speed reference for the last detection waveform
(unspecified number of detections) is not traced.
The detection waveform is not always the same, so the waveform may be different from those shown above even though
the detection has completed normally.
