Mains voltage

The rated mains voltage set for the inverter has an impact on the operating range of the inverter.

Details

By default, the rated mains voltage in 0x2540:001 (P208.01) is set according to the product code of the inverter.

Check the setting of the rated mains voltage in 0x2540:001 (P208.01). Ensure that it matches the actual mains voltage applied!

Notes regarding the table:

–

The inverter types 400/480 V can be used with different mains voltages. For setting the internal limit values, the rated mains voltage can be set in 0x2540:001 (P208.01) by the user.

–

The inverter types 120 V are designed for a 1-phase 120-V mains voltage and 3-phase 230-V three-phase AC motors. These inverters have an internal DC bus similar to the 230-V inverters. The voltage thresholds correspond to the ones of the 230-V inverters.

–

If the inverter is reset to the delivery status, the rated mains voltage is also reset to the default setting listed in the table according to the product code.

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.

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 voltage	Undervoltage thresholds			Overvoltage thresholds
Rated mains voltage	Warning threshold	Error threshold	Reset threshold	Warning threshold	Error threshold	Reset threshold
Setting in 0x2540:001 (P208.01)	Setting in 0x2540:002 (P208.02)	Display in 0x2540:003 (P208.03)	Display in 0x2540:004 (P208.04)	Setting in 0x2540:005 (P208.05)	Display in 0x2540:006 (P208.06)	Display in 0x2540:007 (P208.07)

–

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.
