AKD PDMM User Guide | 6.1.1.2 Direct DC Mains Operation
(see Mains Supply Connection (X3, X4) (pg 170) for more information on this connection).
The nominal level of DC voltage applied must be compatible with the voltage fault levels in the drive. You
must also consider voltage variations in the DC power supply above and below the nominal value so that
nuisance faults are avoided.
When you determine the maximum nominal DC voltage applied to the drive, you should also consider the
regeneration circuit, in addition to the over voltage level. Running the drive slightly below the over voltage
level is not possible because the drive does not have the capability to dissipate regenerated energy. This
practice can also be harmful to the regen circuit. A good practice is not to exceed the nominal DC voltage
produced by a standard AC installation. For the AKD PDMM-zzzzz06, 340 Vdc is the equivalent DC volt-
age for a 240 Vac supply and for the AKD PDMM-xxxxx07, 680 Vdc is the equivalent DC voltage for a 480
Vac supply.
The voltage fault levels are also shown in the Power screen and depend on the voltage level of drive used.
Voltage ranges are as follows:
Model Under Voltage Level Over Voltage Level
AKD PDMM-
zzzz06
90 Vdc 420 Vdc
AKD-zzzz07 380 Vdc 840 Vdc
You can view bus voltage values in the Power screen as shown below:
