APPENDIX D: THE MACHINE WORKING MODES PAGE 33
SENSITIVE MODE
DNC in Mode
The functioning is identical to adjustment mode, except that the return to the
TDC is made in one movement.
DNC in or Mode
The press works in the conventional way, that is:
High speed approach
Deceleration
Safety stop (if the mode requires it)
Bending
Bottom dead center
It is at the bottom dead center (BDC) that the differences appear.
The DNC remains under pressure at the bottom dead center until the descent
command disappears, and this indifferently to the dwell time at BDC.
When the descent command is suppressed, the DNC remains at the BDC
without pressure or descent command, until reception of a rise command
which it executes immediately.
AUTOMATIC MODE
This mode functions in a similar way to sensitive mode, except that the
raising of the beam is made automatically once the dwell time programmed
in the current sequence has elapsed.
This even if the descent command remains active.
NB: In all these modes the ascent command has priority. It is executed
immediately on its reception.
