COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
1.8.2
RESISTANCE
[Ω]
3
This is the value expressed in ohm of the resistor
connected externally. This parameter is set by the
supplier.
Min=+30Ω, Max=+500Ω
1.8.3
POWER NOM [W]
3
Rated power that can be dissipated by the external
resistor. This datum is set by the supplier.
Min=0W, Max=+20000W
1.8.4
RTH [°C/W]
3
Thermal coefficient of the external resistance. It
represents the temperature increase, expressed in
°C, depending on the power that the resistor must
dissipate, expressed in W.
The best dissipation conditions are possible with low
values of this constant.
This datum is set by the supplier.
Min=+0.1°C/W, Max +10.0°C/W
1.8.5
MAX TEMP
[°C]
3
Maximum temperature that can be reached by the
external resistor. If this limit is overtaken, the error
“Brake resistance temperature too high” is displayed.
This datum is set by the supplier.
Min=0°C, Max=+350°C
1.8.6
ENV TEMP
[°C]
3
Average ambient temperature at which the external
resistor is situated.
Min=0°C, Max=+150°C
