Mains voltage
The rated mains voltage set for the inverter has an impact on the operating range of the inver-
ter.
Details
By default, the rated mains voltage is set in
0x2540:001 (PAR 208/001)
according to the inver-
ter type code.
Check the setting of the rated mains voltage in
0x2540:001 (PAR 208/001)
.
Ensure that it matches the actual mains voltage applied!
The following results from the rated mains voltage set:
•
the error threshold for monitoring the DC-bus voltage and
•
the voltage threshold for braking operation ("brake chopper threshold").
Monitoring of the DC-bus voltage
•
The warning thresholds for monitoring are adjustable.
•
The error thresholds and reset thresholds for monitoring result from the rated mains volt-
age set:

•
If the DC-bus voltage of the inverter falls below the undervoltage error threshold, the "Trou-
ble" response is triggered.
•
If the DC-bus voltage of the inverter exceeds the overvoltage error threshold, the "Fault"
response is triggered.
When the undervoltage or overvoltage monitoring function has been activated,
the drive is not restarted automatically.

Default setting depending on the size.
Setting of the warning threshold for monitoring DC bus undervoltage.
•
If the DC bus voltage falls below the threshold set, the inverter out-
puts a warning.
•
The warning is reset with a hysteresis of 10 V.
