13.3.15 46:Low voltage
Resolution Level Response Fault counter
A problem with the supply
voltage or DC link voltage
was detected.
• Cause 1: Parameter-
ized in U00 and U01
• Cause 2: Warning with
10 s warning time
• Cause 3: Malfunction
The parameterized malfunction reaction in the
A29 parameter for cause 1 and 2. For cause 3, the
motor always coasts except when U30 Emergen-
cy stop is activated.

Cause Description Measure Acknowledgement
1:low Voltage The value in E03 DC link voltage has
fallen below the value parameterized
in A35 Undervoltage limit.
Check whether the supply voltage
corresponds to the specification.
Can be acknowledged for mal-
function level by switching the
device off/on or programmed
acknowledgement.
2:network phase The line monitoring has detected that
a phase is missing when the power
stage is switched on.
Check the line fuse and wiring.
3:drop in network If the line monitoring detects that the
line is missing, the load relay is im-
mediately switched off. Normal oper-
ation is maintained. If the line return
of the power stage is still switched
on, a malfunction is triggered after
0.5 s.
Check whether the supply voltage
corresponds to the specification or
whether there is a power failure.
