When performing the press process with the “stroke” return stroke criterion,
primarily the "Returnstroke Stroke" parameter and secondarily the
"Returnstroke Force" parameter are monitored.
Select the "Data Input" system function key.
Select the "Mode: F=0, s=1, t=2, m=3" parameter.
Enter the value "1".
If in a press process the set stroke is not reached, but the set force is
exceeded, the error message: "P1:RS force exceeded!" is displayed.
When performing the press process with the return stroke criterion “time“,
the press moves to the BDC position. When the time set in parameter
"Returnstroke Time" has expired, the press moves to the TDC position.
Select the “Data Input” system function key.
Select the "Returnstroke Time" parameter.
Enter the time after which the return stroke has to be started.
Select the “Mode: F=0, s=1, t=2,m=3" parameter.
Enter the value “2”.
If in a press process the BDC position is not reached, the error message
"BDC not reached->ACK“ appears.
When the press process is performed with the return stroke criterion
“manual“ the press moves to the BDC position. The press remains in the
BDC position until it is acknowledged by means of the external luminous
button. Then the press moves to the TDC position.
Select the “Data Input” system function key.
Select the “Mode: F=0, s=1, t=2,m=3" parameter.
Enter the value “3”.
Stroke takeover (only two-hand control)
The stroke takeover is the moment of the working stroke from which the
closing movement of the working stroke is no longer interrupted upon
releasing the two-hand control.
This stroke takeover has to be set in such a way that the dangerous closing
movement is finished upon reaching this switch.
A dangerous closing movement is that part of the movement of closing tools
that may cause injures. It is finished, when moving parts and fixed parts
have approached each other to such an extent that no more injury is
possible (6 mm).
