126 List Manual (LH2), 07/2016, A5E03263479A
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] = Reduced at the start of precharging
[1] = Regular
Dependency: Refer to: F30021
Note: The parameter only applies to booksize and chassis power units.
Deactivating the ground fault monitoring:
- Sequence: --> p0287[1] = 0 --> p0287[0] = 0
- irrespective of the firmware version of the power unit.
Sets the thresholds:
- the prerequisite is at least firmware version 2.2 of the power unit.
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/velocity or torque/force 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
1: No reduction shutdown when overload threshold is reached
2: Reduce the pulse frequency and output current
3: Reduce the pulse frequency
10: Automatic output current reduction
12: Automatic pulse frequency and output current reduction
13: Automatic pulse frequency reduction
