Power unit temperatures
°C
Float
Description: Displays the temperatures in the power unit.
Index:
• [0]: Inverter maximum value
• [1]: Depletion layer maximum value
• [2]: Rectifier maximum value
• [3]: Air intake
• [4]: Interior of power unit
• [5]: Inverter 1
• [6]: Inverter 2
• [7]: Inverter 3
• [8]: Inverter 4
• [9]: Inverter 5
• [10]: Inverter 6
• [11]: Rectifier 1
• [12]: Rectifier 2
• [13]: Depletion layer 1
• [14]: Depletion layer 2
• [15]: Depletion layer 3
• [16]: Depletion layer 4
• [17]: Depletion layer 5
• [18]: Depletion layer 6

[19]: Cooling unit liquid intake
Dependency: Refer to A01009
Notice: Only for internal Siemens troubleshooting.
Note:
The value of -200 indicates that there is no measuring signal.
• r0037[0]: Maximum value of the inverter temperatures (r0037[5...10]).
• r0037[1]: Maximum value of the depletion layer temperatures (r0037[13...18]).
• r0037[2]: Maximum value of the rectifier temperatures (r0037[11...12]).
The maximum value is the temperature of the hottest inverter, depletion layer, or rectifier.

Torque setpoint total Nm Float
Description:
Displays and connector output for the torque setpoint at the output of the speed controller (before
clock cycle interpolation).
Index:
• [0]: Unsmoothed
•
[1]: Smoothed
r0296
DC link voltage undervoltage threshold
V
U16
Description:
Threshold to detect a DC link undervoltage.
If the DC link voltage falls below this threshold, the drive unit is tripped due to a DC link undervoltage condi-
tion.
Note: The value depends on the device type and the selected device rated voltage.
r0297
DC link voltage overvoltage threshold
V
U16
Description:
If the DC link voltage exceeds the threshold specified here, the drive unit is tripped due to DC link
overvoltage.
Dependency: Refer to F30002.
r0311
Rated motor speed
rpm
Float
Description: Displays the rated motor speed (rating plate).
