PrgE
This parameter defines the approach direction/search direction of the reference cam.
At power–on, the axis can be located in front of or at the reference cam.
Assumption: The axis is located in front of the reference cam.
When starting reference point approach, the reference cam is searched for in the direction
specified in this parameter.
Assumption: The axis is located at the reference cam
When starting the reference point approach, the reference cam is already known. The axis
now moves away from the reference cam in the direction opposite to that entered in this pa-
rameter and continues the reference point approach.

The reference cam is in the negative direction

Note:
For an axis without reference cam (P0173 = 1), referencing is started with phase 2 (synchroniz-
ing with the zero reference pulse).
The approach direction when searching for the zero pulse is defined using P0166.

PrgE
... specifies the maximum distance the axis can traverse from starting the reference point
approach in order to find the reference cams.
Note:
When a fault condition occurs, the axis remains stationary and fault 160 is signaled (reference
cam not reached).
