SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Displays the internal resistance of the power unit (IGBT and line resistance).
Description: Sets the shutdown thresholds for the ground fault monitoring.
The setting is made as a percentage of the maximum current of the power unit (r0209).
Index: [0] = Threshold at which pre-charging starts
[1] = Threshold at which pre-charging stops
Dependency: Refer to: p1901
Refer to: F30021
Note: This parameter is only relevant for chassis power units.
Description: Displays the actual maximum output current of the power unit taking into account derating factors.
Description: Sets the response to a thermal overload condition of the power unit.
The following quantities can result in a response to thermal overload:
- heat sink temperature (r0037.0)
- chip temperature (r0037.1)
- power unit overload I2T (r0036)
Possible measures to avoid thermal overload:
- reduce the output current limit r0289 and r0067 (for closed-loop speed or torque control) or the output frequency
(for U/f control) indirectly via the output current limit and the intervention of the current limiting controller).
- reduce the pulse frequency.
A reduction, if parameterized, is always realized after an appropriate alarm is output.
Value: 0: Reduce output current or output frequency
1: No reduction shutdown when overload threshold is reached
2: Reduce I_output or f_output and f_pulse (not using I2t)
3: Reduce the pulse frequency (not using I2t)
