Step 1
:
The machine is at PMSM. The closing, by means of the cam
S.A.
, of the contact of PMSM
sets the connected input to state ON and causes the passage of the two OSSD outputs to
state ON, with the necessary condition that DSP LASER is collimated and in operating
mode 1. This allows the use of the high-speed downstroke. The machine is ready for the
check of the stop space.
Phase B
:
The closing at high speed is commanded and, then, the FAST DOWNSTROKE signal,
which it depends from, is present on the relevant input. The closing of the press until the
interception of the limitswitch VSA must take place in continue mode, without interruptions.
Step 2
:
The cam reaches the limitswitch VSA which determines the passage of the OSSD outputs
of DSP LASER to state OFF. The circuit of the press-brake inhibits the high speed, causing
the stop of the machine. However the table makes a residual stroke, due to inertia, equal to
the value of the stop space.
