Block 4
Block 1 is immediately rejected because the start condition "traverse
up to cam" is rejected.
Fig. 5-8 Reference to occurring zero mark, start at the cam
Referencing is performed at the zero mark occurring after leaving
the cam.
The function "reference to occurring zero mark" can be assigned to an
individual traversing block (with the No.: X ) of the drive.
The activation takes place with P80:X.14 = 1.
The corresponding traversing block (relative position/absolute position/
speed–controlled) is executed until occurrence of a zero mark. The
drive is referenced at the zero mark to the position given in the signal
position (P85:X).
If the function is executed in connection with a positioning block (rela-
tive position/absolute position), the specified path must pass over a
zero mark.
A speed–controlled block stops at the zero mark.
Note
The function "Reference to occurring zero mark" cannot be used
simultaneously with one of the following functions in a traversing block:
S
"Flying measurement"
S
"Flying actual value setting" (P80:X.10 = 1)
S
"Set reference position"
Using the function with the help of the parameterizing and
start–up tool SimoCom A (from version 4.02.xx)
The reference dialog allows the configuration of a referencing program
with 4 traversing blocks, in accordance with the diagrams shown in
the dialog.
