Power View

From the Power screen, you can view and configure the drive power settings as follows.

Section	Element	Description
Voltage	VBus Gauge	A graphical gauge representation of the DC bus voltage, including ranges for warnings and faults. The slider adjusts the zoom level of the gauge.
	Under Voltage Fault Threshold	Sets the value at which an under voltage fault will occur
	Under Voltage Warning Threshold	Sets the value at which an under voltage warning will occur
	Actual Value	Displays the current actual voltage value
	Over Voltage Warning Threshold	Sets value at which an over voltage warning will occur. Setting a value of 0 generates no warning.
	Over Voltage Fault Threshold	Sets value at which an over voltage fault will occur
	Under Voltage Fault Mode	Sets the behavior for when an under voltage fault are monitored.

See Regeneration for more information about regen resistors and sizing regen resistors. 

Operating Voltage

Operating voltage can be selected by the user to allow 480VAC drives to work on 240VAC input supplies.

A power-cycle is needed after changing the value and saving the parameter on the NV memory of the Drive, since the voltage thresholds mentioned above are read during the boot-sequence of the drive.
