When a cabinet is designed, it must satisfy the environmental conditions
described in Section 3.1. In addition, the magnetic interference on the
screen, noise resistance, and maintenance requirements must be
considered. The cabinet design must meet the following conditions :
D The cabinet must be fully closed.
The cabinet must be designed to prevent the entry of airborne
dust,coolant,and organic solvent.
D The cabinet must be designed so that the permissible temperature of
each unit is not exceeded. For actual heat design, see Section 3.4.
D A closed cabinet must be equipped with a fan to circulate the air
within. (This is not necessary for a unit with fan.)
The fan must be adjusted so that the air moves at 0.5 m/sec along the
surface of each installed unit.
CAUTION
If the air blows directly from the fan to the unit, dust easily
adheres to the unit. This may cause the unit to fail. (This
is not necessary for a unit with fan.)
D For the air to move easily, a clearance of 100 mm is required between
each unit and the wall of the cabinet. (This is not necessary for a unit
with fan.)
D Packing materials must be used for the cable port and the door in order
to seal the cabinet.
D The display unit must not be installed in such a place that coolant
would directly fall onto the unit. The control unit has a dust–proof
front panel, but the unit should not be placed in a location where
coolant would directly fall onto it.
D Noise must be minimized.
As the machine and the CNC unit are reduced in size, the parts that
generate noise may be placed near noise–sensitive parts in the
magnetics cabinet.
The CNC unit is built to protect it from external noise. Cabinet design
to minimize noise generation and to prevent it from being transmitted
to the CNC unit is necessary. See section 3.5 for details of noise
elimination/management.
D When placing units in the cabinet, also consider ease of maintenance.
The units should be placed so that they can be checked and replaced
easily when maintenance is performed.
D The hard disk drive and floppy disk drive must not be installed near
the source of a strong magnetic field.
D The installation conditions of the I/O unit and connector panel I/O
module must be satisfied.
To obtain good ventilation in the module, the I/O unit and connector
panel I/O module must be installed in the direction shown in the
following figure. Clearances of 100 mm or more both above and
below the I/O unit are required for wiring and ventilation.
Equipment radiating too much heat must not be put below the I/O unit
and connector panel I/O module.
