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
voltage set:
Rated mains volt- Undervoltage thresholds Overvoltage thresholds

• If the DC-bus voltage of the inverter falls below the undervoltage error threshold, the
"Trouble" response is triggered. The motor behaves in accordance with 0x2838:002
(P203.02).
• If the DC-bus voltage of the inverter exceeds the overvoltage error threshold, the
"Fault" response is triggered.
The motor does not restart automatically after the overvoltage monitoring function
has been activated.
