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]
