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
POINT
approx. 50%, so the heating values inside the panel are half the values shown
above.
Total heating value = (15 + 31) + (26 + 63) = 135 [W]
Heating value in panel = 15 x 0.5 + 26 x 0.5 = 20.5 [W]
