6.1.1 Drive Setup for Power and Bus

The Power screen allows you to confirm Power Bus settings and accommodates external regeneration
needs if required. Nothing is required for this screen if you have no regeneration requirements. Review the
data on the screen to be certain the bus voltage is at the appropriate levels you expect (approximate input
line AC voltage * 1.4). The other values are the appropriate limits for over voltage and under voltage for the
particular drive. You can select the undervoltage fault mode to trigger either only when the drive is enabled
or always.
From the Power screen, you can view and configure the drive power settings as follows:

6.1.1.1 Operating Voltage

Operating voltage can be selected by the user to allow AKD PDMM-xxx07 (480Vac) drives to work on
240Vac input supplies.
The VBUS.HALFVOLT parameter has an effect on the following voltage-thresholds:
DC-bus over-voltage threshold (see VBUS.OVFTHRESH (pg 445)).
l
The regen-resistor enable/disable voltage thresholds.
l
The inrush-relay enable/disable voltage thresholds.
l
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.

6.1.1.2 Direct DC Mains Operation

Direct DC input is available on all standard AKD PDMM models. The DC input should be run into the AC
input connection. Positive and negative DC lines should use L1 and L2 connections (polarity is not crit-
ical). L1 and L2 connections are found on either the X3 connector or the X4 connector depending on the
model.
