Abort manual loading/unloading
Description
This function block aborts the loading/unloading operations at a magazine location. To do this,
it evaluates the function flag (loading or unloading from DB 144/DW 6).
If the function flag = "Loading":
The function block declares all D numbers of the reference list of the loading line (DW 2), with
the exception of the first D number, to be unassigned and deletes them in the reference list;
i.e. all cutting edges of the tool, except the first cutting edge, are deleted. The loading line
remains unchanged with its one cutting edge. The old location is declared unassigned only if
the preliminary function "Loading" is selected, FB 166 "Load spindle" was processed without
error and bit 117.1 "Acknowledge spindle" is set. The old location is declared unassigned only
if the preliminary function "Loading" is selected, FB 166 "Load spindle" was processed
without error and bit D117.1 "Acknowledge spindle" is set.
If the function flag = "Unloading":
The data in the loading line is deleted. If only one D number is entered in the reference list of
the loading line, the D number is deleted.
Special features:
The dynamic softkey signal (F234.4) must be routed by the user program either to the positive
user acknowledgement (F237.4) or the negative user acknowledgement (F236.4) within the
same cycle. The user acknowledgement may not be present for more than one cycle. This is
achieved by logic operation with the dynamic softkey signal.
