Parameter 16-31 System Temp.
Table 849: Parameter 16-31 System Temp.
16-31 System Temp.
Default value: 0 °C
Parameter type: Range, -128 - 127 °C
Setup: All setups
Conversion index: 100
Data type: Int8
Change during operation: True
Shows the highest internal system temperature. In the smaller enclosure sizes (A–C), the system temperature matches the control
card temperature measurement in parameter 16-39 Control Card Temp. In the larger enclosure sizes (D–F), the system temperature is
the highest temperature measured on hardware components with temperature sensors, for example, the power card(s).

16-33 Brake Energy Average
Default value: 0 kW
Parameter type: Range, 0 - 10000 kW
Setup: All setups
Conversion index: 0
Data type: Uint32
Change during operation: False
View the brake power transmitted to an external brake resistor. The mean power is calculated on an average level based on the
selected time period within parameter 2-13 Brake Power Monitoring.
Parameter 16-34 Heatsink Temp.
