Teach Commands 

By using teach commands, the setpoints of the switching signal channel SSC1 can be defined by teach-in 
the position of the object or reference. 
Next to teach-by-value which can be applied as described in section 4.3.1, using teach commands makes it 
easy to compensate individual variations such as mechanical and mounting tolerances. 
 
There are two different procedures available – static or dynamic – which can be individually chosen 
independent of the switching mode of the selected SSC 

- 

Static:  

Defines the setpoints by teach-in the positions of non-moving objects 

- 

Dynamic:   For moving and small objects. Analyzes the minimum and maximum distances within 
a time frame to define the setpoints.  

The teach-in procedures are described more detailed in section 5.2 (Static) and 5.3 (Dynamic). 
 
The switching behavior of each switching signal channel depends on the configuration (Switching Mode, 
Channel Logic, …) described in section 4.3.2. 
 

5.1 

Teach Channel Selection, TPO & Teach Status 

The described teach commands can be applied to individual switching signal channels. Before proceeding 
with the teach-in procedure, make sure to select the SSC that should be addressed. 
 
Furthermore different information are available to indicate the current mode and teach-in state of the 
selected switching signal channel to help to execute the right commands described in section 5.2 and 5.3.
