ENSITIVE 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 centre
It is at the bottom dead centre (BDC) that the differences appear.
The DNC remains under pressure at the bottom dead centre 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.
A
UTOMATIC MODE
This mode functions in a similar way to sensitive mode, except that the rais-
ing 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 immedi-
ately on its reception.
