3.6.4 Response, effective direction 
Response 
The diagram below shows the ON and OFF switching characteristics of cams, 
without hysteresis, derivative time or OFF delay: 
The switching characteristics are determined only by the position (setpoint position 
or actual position). 
Effective direction 
You can define an effective direction when you enable the cam. The cam is only 
switched if the motion corresponds with the set effective direction. 
Options available: 
Effective direction  Response 
Positive  The cam is switched only with positive direction of the motion. 
Positive and 
negative 
The cam is switched independent of the motion direction. 
Negative  The cam is switched only with negative direction of the motion. 
Current sense of 
rotation 
With this setting, the cam switches only in the currently set direction 
of rotation. Standstill is a positive direction of rotation. 
The diagram below shows the effects of the effective direction (effective direction 
Positive)
