Explanation of CNC-RDY timing diagram
•
Y-axis status. The Y-axis status is the number of the Y-axis control program, which depends
on the Y-axis command inputs. The number is shown on the service row (when activated) in
the header of the screen.
•
Upper dead point. Y-axis output indicating that press beam is in the upper dead point
position.
•
X-axis at programmed position. This line shows the actual X-axis position. This is the same
as the programmed position.
The start button must be pressed (1). When in this case the press beam is in the upper dead point
(output active) and the X-axis reaches the programmed position (2) the CNC-RDY output
becomes active (3). The CNC-RDY output stays active during fast closing of the press beam (4),
pressing (5) (when no X-axis retraction is programmed), dwell time (6) and decompression (7).
The CNC-RDY becomes inactive after decompression of the beam (ER output active) at the step
change position where the X-axis moves to the next programmed position. Depending on the X-
axis code this can take place at:
•
end of decompression;
•
mute (passed in opening direction);
•
upper dead point.
The CNC-RDY signal becomes active again (9) when the X-axis is at its programmed position
and the Y-axis is in the upper dead point.
CNC-RDY signal during pressing with retraction programmed
There are two situations during pressing with rectraction programmed (point 5 of CNC-RDY
cyclus).
•
The press beam does not wait at the pinching point for X-axis retraction to complete (X-axis
code < 10). The CNC-RDY output stays active while the X-axis moves to the retract
position.
•
The press beam stops at the pinching point and waits until X-axis retraction is completed (X-
axis code > 10). The CNC-RDY output stays active while the X-axis is moving to the retract
position. The press beam moves again when the X-axis has reached the retract position.
There is also a third situation, but this is an option.
•
The press beam stops at the pinching point and waits until the X-axis rectraction has been
completed (X-axis code > 10). The CNC-RDY output is
off while the X-axis is moving to
the retract position. The CNC-RDY output becomes active again when the X-axis has
reached the retract position.
