8.2.10 DC−bus voltage
In C0173 the mains voltage and the DC−bus voltage are set. The switching
thresholds for overvoltage and undervoltage are based on these settings.

C0173 = 1: Lenze setting
If the DC−bus voltage exceeds the upper switch−off threshold set in C0173,
the OU message is triggered.
If the DC−bus voltage falls below the lower switch−off threshold set in C0173,
the LU message is triggered.
ƒ An undervoltage message > 3 seconds is interpreted as an operating
state (e.g. mains switched off) and entered in the history buffer. The
entry is, however, deleted as soon as the cause has been eliminated
(e.g. mains switched on again).
This operating state can occur if the control module is already supplied
externally via terminals X5/39 and X5/59, but the mains voltage is not yet
switched on.
ƒ An undervoltage message < 3 seconds is interpreted as a fault
(e.g.mains fault), entered in the history buffer and saved.
8.2.11 External error (EEr)
A HIGH signal at DCTRL−TRIP−SET triggers the EEr fault.
You can, for example, connect the digital input DCTRL−TRIP−SET with an
input terminal (X5/Ex). In this way an external encoder can trigger the EEr
fault.
The response can be set under C0581.
