6.4.13
Extended AC Voltage Range Operation
The standard AC voltage range maximum setting for line-to-neutral voltage programming is
300Vac rms. This setting is equivalent to 520V line-to-line in three-phase mode. However,
keep in mind that some V/F combination limits will be in effect (both voltage and frequency
cannot be high at the same time). For examples, the user can set a frequency user limit of
3000Hz if the programmed voltage is low enough. The same for the voltage, it can be set to
312Vrms if the frequency is low enough (800Hz or less).
For applications where a higher AC voltage is required, extended voltage operation up to
320V is supported with some restrictions. These restrictions are determined by the
maximum voltage setting programmed:
6.4.13.1
300 – 305 V - Max Voltage 305VL-N / 528VL-L
This setting reflects a 10% over voltage for 277V

Higher Voltage Settings
For applications requiring more than 312V L-N, refer to the “SOURce:VOLTage:EXTend”
command in the programming section of this manual.
6.4.13.4
Extended Voltage Range Power Limit Setting
Applicable output power restrictions as stated above will result in adjustment of the
programmed kW and kVA power limits in the PROGRAM screen. This occurs automatically
when programming an AC voltage value higher than 300 and is based on the value set and
