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.
