therMals: power dIssIpatIon
The top chart on this page shows the internal power dissipation for one axis of the BE2 under differing
power supply and output current conditions. The +HV values are for the average dC voltage of the drive
power supply. The lower chart shows the temperature rise vs. power dissipation under differing mounting
and cooling conditions.
ToTal PoWer dISSIPaTIon
use this chart to find the total power
dissipation for both axes.
Example:
Power supply HV = 65 Vdc
Axis 1 current = 7.5 A, axis 2 = 9.0 A
Total current = 16.5 A
Total dissipation = 19 Watts
therMals: MaXIMuM operatIng teMperature Vs. dIssIpatIon
use this chart to find the maximum
operating temperature of the drive under
differing mounting and cooling conditions.
Example:
Using the 19 W value from the calculations
above, draw a vertical line. This shows
that 24 C is the maximum operating
temperature for nHSnf, and that any of
the other mounting/cooling options will be
sufficient for operation up to the maximum
ambient temperature of 45 C.
HSf = Heat Sink (with) fan
nHSf = no Heat Sink (with) fan
HSnf = Heat Sink no fan
nHSnf = no Heat Sink no fan
