5.5.7 Lock areas
General
Lock areas are basically used to provide
sofeware-side backup for the mechanical
functions in the robot system and the injection
moulding device. The robot cannot enter these
areas.
Users are given a total of 5 lock areas, whereby
Lock area 1 is a fixed mould area. Lock area 2
is for the tool closing side and Lock area 3 for
the tool nozzle side.
Lock areas 4 and 5 can be used as required. A
lock area is fully defined by specifying the start
and end positions.
The start coordinates "-" of the lock area define
the minimum coordinate for each axis.
The end coordinates "+" of the lock area define
the maximum coordinate for each axis.
If all the "-" and "+"positions for a single lock
area of the three main axes are entered, this
produces a cube containing the lock area as
shown in the diagram.
Lock area 1 (mould area) is only treated as a
lock area provided the mould is not fully open.
This lock area is deactivated by the ”Start
handling device procedure” or ”Tool at
intermediate stop” (IMM interface) signal in order
to allow the vertical axis to be inserted between
the two mould halves.
It is important to define the mould area. This is
because the ”Enable close mould” signal is not
sent to the IMM in Set-up or Automatic mode and
the robot cannot be started automatically
(”Operating area violation” fault).
An ”Operating area violation” fault occurs when
all the axes ”violate” a lock area.
