伺服驅(qū)動模塊KDS在冷運行技術(shù)方面具有優(yōu)勢模塊化單元的大部分熱損失直接輸出,并且不會在控制柜內(nèi)積聚。這就是為什么冷運行技術(shù)版本可嵌入小型機柜或外殼,無需需要通過昂貴的熱量進行廣泛的熱量傳輸交換器??墒褂猛獠匡L(fēng)扇強制通風(fēng),該風(fēng)扇可作為如果功率要求更高,則增加一組。
通風(fēng)裝置的電氣部件保護性地位于控制柜,如圖41所示。電源的散熱器部分和風(fēng)扇轉(zhuǎn)子位于控制柜或外殼外部。裝置通過安裝框架安裝在控制柜的后壁,使驅(qū)動器散熱片面板伸出控制柜。
控制柜中的開口用密封墊密封冷運行型的安裝法蘭(參見安裝圖,圖52,第5.2.4章)。伺服驅(qū)動模塊和外部風(fēng)扇安裝并可在控制柜內(nèi)部更換。

Servo drive module KDS in cold-running technology has the advantage
that most of the heat loss of the modular units is fed directly out and does
not accumulate inside the control cabinet. This is why the cold-runnng
technology version can be built into small cabinets or housing without
necessitating the extensive transmission of heat via an expensive heat
exchanger.
Ventilation can be forced using an external fan, which can be supplied as
an additional set, if power requirements are greater.
The electrical parts of the ventilation are protectively located within the
control cabinet, as depicted in Figure 41. The heatsink of the power
section and the fan rotor are outside of the control cabinet or housing.The units are mounted by means of a mounting frame in a space on the
back wall of the control cabinet in such a way that the drive heatsink with
panelling juts out of the control cabinet.
The opening in the control cabinet is tightly sealed with a gasket at the
mounting flange of the cold-running version (see mounting drawing,
Figure 52, in Chapter 5.2.4). The servo drive module and the external fan
are mounted and can be exchanged on the inside of the control cabinet.
The data listed on the data sheets and selection lists are valid without
restriction, if the servo drive module is operated within an ambient
temperature range inside the control cabinet of +5 to +45°C.
Maximum permissible ambient temperature is +55°C.
The values for mean motor current and torque listed in the data sheets
are reduced by 2% per degree Celsius or Kelvin of temperature change
within the temperature range of +45 ... 55°C.
Maximum mounting altitude is 1000 meters above sea level. The
following diagram depicts the reduction in values for mean motor current
and torque at higher altitudes:The minimum clearance to adjacent units must be absolutely maintained
to guarantee sufficient heat transmission and circulation.
The temperature within the mounting area (interior) of the control cabinet
should not exceed 45°C. Forced ventilation, to avoid dammed up heat,
as well as a reduction in the max. unit current, by 2.5% / K., become
necessary with higher values, up to max. 55°C.
If a cing device is used, then the internal temperature of the control
cabinet must be maintained at a minimum of 2 degrees Celsius above
external temperatures to prevent bedewing. Bedewing of a printed
circuit board can cause drive failure.
Heat-producing built-in parts should not be installed directly underneath
the servo drive module
