6.1 Power
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:
Button or Dialog
Box Description Parameter
Measured Bus
Voltage Reads the current DC bus voltage. VBUS.VALUE (pg
448)
Over Voltage
Fault Level Reads the over voltage fault level. VBUS.OVFTHRESH
(pg 445)
Under Voltage
Fault Level Reads the under voltage fault level. VBUS.UVFTHRESH
(pg 447)
Under Voltage
Fault Mode Sets under voltage mode. VBUS.UVMODE (pg
447)
Operating Volt-
age Sets the operating voltage. VBUS.HALFVOLT
(pg 445)
Regen Resistor
Type Sets the regen resistor type to either - 1-External Regen or 0-
Internal Regen (if available) .
REGEN.TYPE (pg
425)
Regen Power Reads the regen power (only visible for external regen). REGEN.POWER (pg
423)
External Regen
Resistance Sets the external, user-defined regen resistor resistance
(only visible for external regen). REGEN.REXT (pg
424)
External Regen
Heat Up Time Sets the external regen resistor thermal protection time con-
stant (only visible for external regen). REGEN.TEXT (pg
424)
External Regen
Power Sets the regen resistor's power fault level for an external
regen resistor (only visible for external regen). REGEN.WATTEXT
(pg 426)
See Regeneration (pg 36) for more information about regen resistors and sizing regen resistors.
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:
l
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.
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.
