When a cabinet is designed, it must satisfy the environmental conditions
described in Section 3.1. In addition, the magnetic interference on the
CRT 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.
Cabinets that let in air may be designed for the servo amplifier and
servo transformer provided that they (This applies only to cabinets not
certified for the CE marking, however.) :
- Use an air filter on the air inlet ;
- Place the ventilating fan so that it does not blow air directly toward
the unit;
- Control the air flow so that no dust or coolant enters the air outlet
D Design the cabinet so that the allowable environment temperature
ranges for each unit accommodated in it will not be exceeded.
For details of the thermal design, see Sections 3.4 to 3.5.
D A closed cabinet must be equipped with a fan to circulate the air
within.
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.
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 setting and display unit (CRT/MDI and etc.) must not be installed
in such a place that coolant would directly fall onto the unit. The
setting and display unit has a dustproof 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 noisesensitive 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 3.7 for details of noise
elimination/management.
D The units must be installed or arranged in the cabinet so that they are
easy to inspect and maintain.
When, especially, the I/O Link slave function is used, its cable is
connected at the bottom of the unit. So, be sure to allow a space large
enough to attach and detach the cable easily.
