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 mains voltage applied!

Notes regarding the table:

–

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

–

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 factory settings, the rated mains voltage is also reset to the default setting (see table).

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 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.

–

Without external 24-V supply: the motor behaves according to 0x2838:002 (P203.02).

–

With external 24-V supply: at undervoltage, the motor behaves according to "Trouble" response.

–

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.
