CAUTION
The ambient temperature condition for the power supply unit or the drive units is
55°C or less. Because heat can easily accumulate in the upper portion of the
units, give sufficient consideration to heat dissipation when designing the panel.
If required, install a fan in the panel to agitate the heat in the upper portion of the
units.
1-3-3 Prevention of entering of foreign matter
Treat the cabinet with the following items.
• Make sure that the cable inlet is dust and oil proof by using
packing, etc.
• Make sure that the external air does not enter inside by
using head radiating holes, etc.
• Close all clearances.
• Securely install door packing.
• If there is a rear cover, always apply packing.
• Oil will tend to accumulate on the top. Take special
measures such as oil-proofing to the top so that oil does
not enter the cabinet from the screw holds.
• After installing each unit, avoid machining in the periphery.
If cutting chips, etc., stick onto the electronic parts, trouble
may occur.
• When using the unit in an area with toxic gases or high
levels of dust, protect the unit with air purging (system to
blow clean air so that the panel's inner pressure is higher
than the outer pressure).

POINT
1. Attach packing around the square hole to provide a seal.
2. A square hole does not need to be machined on the MDS-C1-V1-10 or
smaller, MDS-C1-V2-1010 or smaller and MDS-C1-SP-15 or smaller units.

1-3-5 Heating value
Each heating value is calculated with the following values.
The values for the servo drive unit are for a stall output, and the values for the spindle drive unit are for
a continuous rated output. The value for the power supply unit includes the AC reactor's heating value.

POINT
Design the panel's heating value taking the actual axis operation (load rate) into
consideration. With a general machine tool, the servo drive unit's load rate is
approx. 50%, so the heating values inside the panel are half the values shown
above. (Excluding the power supply and spindle drive unit.)
When using MDS-C1-CV-260, MDS-C1-SP[]-185 and MDS-C1-V2-3535
Total heating value = (40 + 220) + (62 + 280) + (51 + 209) = 862 [W]
Heating value in panel = (40) + (62) + (51 × 0.5) = 127.5 [W]
