REPOS acknowledgement operations
With the channel-specific VDI signal:
DB21, ... DBX319.0 (REPOSMODEEDGEACKN)
if a "handshake" is established by the interface signal:
DB21, ... DBX31.4 (REPOSMODEEDGE)
recognized by the NC and acknowledged with DB21, ... DBX319.0 to the PLC.
Note
If NCK has not yet acknowledged the interface signal:
DB21, ... DBX31.4 (REPOSMODEEDGE)
with the interface signal:
DB21, ... DBX319.0) (REPOSMODEEDGEACKN)
, a RESET in this situation cause the program to abort and the REPOS that is to be used to
control the REPOSPATHMODE can no longer take place.
A REPOSMODE specified by the PLC is acknowledged by the NCK with the interface
signals:
DB21, ... DBX319.1-319.3 (Repos Path Mode Ackn0 to 2)
and
DB31, ... DBX10.0 (Repos Delay)
with:
DB31, ... DBX70.2 (Repos Delay Ackn)
in the following way:
A part program is stopped at N20 (→ time (2) in figure). The NCK stops according to the
braking ramp. After the PLC has specified the REPOSPATHMODE, the NCK accepts the
REPOSPATHMODE with the 0/1 edge of REPOSMODEEDGE at → Time (3). Repos Path
Mode Ackn remains set until the ASUB is initiated (→ Time (4)). The REPOS command is
started in the ASUB (→ Time (5)). The ASUB RESET block is activated again (→ Time (6)):
