List Manual, 09/2017, A5E33842890
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 precharging starts
[1] = Threshold at which precharging 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)
12:
I_output or f_output and automatic pulse frequency reduction
13:
Automatic pulse frequency reduction
