3.2.2. Installation of Driver Unit
The Driver Unit Model EDD must be fixed so that fins are in the vertical position for natural air-cooling.
Caution : (1) Ambient temperature
Ambient temperatures should be in a range from 0 to 50 [[°C]]. The Driver Unit
cannot be used in excess of 50 [[°C]]. A sufficient space of at least 100 [mm] should
be provided both above and below the Driver Unit in a control cabinet. Operate the
Driver Unit in an environment in which internally generated heat can be dissipated.
If heat is trapped above the Driver Unit, open the space above it to allow for the heat
to dissipate (in this case, also take steps to prevent the entry of dust) or provide a
forced air cooling system.
(2) Dust-proof • Waterproof
Use the Driver Unit in a control cabinet with IP54 or higher. Protect the Driver Unit
from exposure to oil mist, cutting water, cutting dust, coating gas, etc., to prevent
their entry into the Driver Unit through ventilation openings, which may cause
circuit failure.
IP code is specified in the IEC standard and classifies the protection level of
enclosures from the solid contaminant and water.
Explanation of IP54:
Code 5: Dust-proof (protection against external solid contaminant)
Code 4: Waterproof (must not be affected by water splash in any direction.)
Caution : When installing two or more Driver Units for multi-axis combinations,
provide a 10 mm or more space between adjacent Driver Units.
Maintain inside temperature of the enclosure into which the Driver Unit is installed between 0 to 50[°C].
If the alarm P0 (Over heat) occurs frequently, provide a forced cooling to the heatsink.
Refer to “11. Alarm and Warning” for details.
The Driver Unit Model EDD can be attached to a panel using front mounting brackets (optional).
The maximum power loss of the Driver Unit Model EDD is 55 W.
