ANNEX D: THE MACHINE WORKING MODES
3 working modes are generally available at machine level.
The functioning is described hereinafter.
Depending on the manufacturers and the safety standards in force in the
country, the functioning can be different.
Adjustment mode
Sensitive mode
Automatic mode
These modes are independent of the DNC
modes and can
be combined. Exception: the adjustment mode.
ADJUSTMENT MODE
This mode only functions with the DNC in mode.
If this is not the case, the press refuses to descend.
In this mode the table only functions in bending speed with the pressure and
speed programmed in the current sequence.
The top dead centre of the current sequence is active, it is thus not possible to
raise the beam above this point.
On the other hand, the bottom dead centre programmed in the sequence is not
active. Thus only stopping the descent command, or a mechanical stop
(punch in the die), or the lower limit switch will stop the beam in the descent
phase.
