PC NC Maintenance Manual Chapter 1: General Installation and Electrical Connection devices, or outdoors, even if the ambient temperature is within the specified range. Design of the enclosure should be made on the basis that the average temperature increase of air within the enclosure (containing the PC NC unit and other components) should be 10oC below the external air temperature.
Chapter 1: General Installation and Electrical Connection PC NC Maintenance Manual CNC portion, 104W in the servo portion, and 29W in the I/O portion): P ∆Τ= qe = kP .A 246 = 9.9 (oC) 6 x 4.16 Therefore, the above value is within the temperature increase value. When it exceeds 10oC, separate cooling countermeasures must be arranged. (2) Heat Exchanger Cooling Capacity Yaskawa can provide heat exchangers where the cooling capacity is insufficient even with a circulating fan mounted in the enclosure.
PC NC Maintenance Manual Chapter 1: General Installation and Electrical Connection Example: Allowable Heat Generated in the Enclosure with Heat Exchanger The amount of internal heat generated to make the internal temperature under 10oC when the enclosure is equipped with a HEATEX02 Heat Exchanger is expressed by the following equation: P= k.A.∆Τ+ 250 W/10oC = 6 x 4.16 x 10 + 250 = 499 W/10oC Therefore, the amount of internal heat generated must be less than 499W.
