Signal status, description
Note:
Upon an external block change:
S
If the target position in traversing block x has not yet been
reached, an external block change acts like the loss of a start
1
condition in traversing block x.
S
However, if traversing block x+1 has already been selected
as the current traversing block (P48), an external block
change acts on traversing block x+1.
0 Inactive
Active
The traversing block is aborted upon the occurrence of a zero
mark. The reference point is set to the value given in the signal
position.
If this function is used together with a digital input (BERO) that is
1
configured with an additional cam monitoring (P31/P32), refer-
encing only takes place if a cam signal edge has occurred in
accordance with P56.7. If the corresponding signal has not oc-
curred at the digital input, the drive is de–referenced upon reach-
ing the zero mark. In this case, error 711/912 is signaled.
