SENSOR PROGRAMMING
3.6.2. Midpoint TEACH
3.6.2.1. Window Size
The D_OUT > TchMid > WndSize option sets the window size that the Midpoint TEACH uses to set the setpoint one and setpoint two thresholds.
The taught surface must be inside the defined sensing range, and at least one setpoint (with offset applied, if any) must be located within the
sensing range.
The Discrete Output window size is a different setting than the Analog Output window size when defined using the push buttons.
Navigate: MENU > D_OUT > TchMid > WndSize
Remote Input: Available
1) Access the setup mode.
2) Set the window size.
3.6.2.2. TEACH Midpoint
The TchMdPt option sets the midpoint that determines the actual measurement window.
Figure 10: Window and Midpoint Example
The Midpoint TEACH uses both the window size and the TEACH midpoint to
determine the actual measurement window. For example, a window of 200 mm
with a midpoint of 600 mm places the measurement window from 500 mm to 700
mm.
To use Midpoint TEACH:
1) Set the window size.
2) Set the measurement window using TEACH Midpoint.
The Discrete Output Midpoint TEACH and the Analog Output Midpoint TEACH are
independent settings.
