A.4 Derating at T
If the multi-axis system is operated outside the specified maximum ambient temperature (T
put power of the supply unit must be reduced as a function of the higher ambient temperature; this reduc-
tion will have an effect on the current in the DC link connections. This so-called temperature derating is
used to protect parts in the device against overheating.
