1)Reaction to these errors chapter: Function diagrams from inputs and outputs

2)With configuration corresponding chapter : Operating modes and pin functions

3)Only warning respect. status indicator

The error signals are shown as long as there is control voltage (Us), also when the power (DC-Bus) is switched off for safety reasons.
