Product description
36 AX5805
3.6.4 Parameterization and referencing of the safe position
The SLP (Safely Limited Position) and SCA (Safe CAM) safety functions can be used only after the axis has
been homed and the referencing cam has been encountered and the safety position has been referenced.
3.6.4.1 Requirements
An external position (e.g. position of the NC) must be linked with the standard process image (Position
Actual Value) of the AX5805. The external position (e.g. NC Position of the axis) must be referenced/homed
prior to the AX5805 Reference input being turned on. In the case where an incremental encoder is used, the
axis must be homed prior to the referencing input being turned on.
Figure 20: An external position must be linked with the AX5805
A reference cam (e.g. proximity switch) must be connected to the digital inputs/outputs X06 (device front) of
the AX5000. The corresponding number of the digital input (0 to 7) must be entered in the
Reference_Position_Inputpin parameter.
