3.4 Programmed Frequency Steps
The allowed frequency delta for programmed frequency steps is a function of
programmed output voltage and phase angle for models with the V-Option. At
programmed phase angles greater than 90º, and programmed output voltage greater
than 270 VRMS, the allowed frequency step is 45–500 Hz. At programmed phase
angles greater than 90º, and programmed output voltage of 310 VRMS, the allowed
frequency step is reduced to 45–250 Hz. Exceeding the allowed frequency step could
result in a fault shutdown of the unit.
