Referencing
Position Detection and Positioning
The reference cam must start just before or in line with the CCW hardware limit switch
and must project into the limit switch. This ensures that no contact is made with the hard-
ware limit switch during reference travel.
6.6.9 Type 8: Without enable
The reference position is the current position. The arguments in the IPOS
plus®
com-
mand Go0"ZP" or "CAM" and P904 have no effect.
It makes sense to use this type of reference travel with absolute encoders and for drives
that are to be referenced at standstill. For example, the position of a feed axis can be
set to zero when the drive is at a standstill. In this way, the machine operator can tell
where the drive is located within each feed movement.
In contrast to type 5, type 8 reference travel can also be performed when the system
status is not set to "A".
