Min:
0.0 [%]
Max:
100.0 [%]
Factory setting:
[0] 6.0 [%]
[1] 16.0 [%]
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: See also: p1901
