12 Components in the DC bus
The energy flow of a drive system in motor and in generator mode can be controlled via the DC bus
if the inverter is provided with terminals on the DC-bus level. DSD offers components for the oper-
ation in the DC bus:
• Power supply modules for energy supply into the drive system.
• Regenerative power supply modules for energy supply into the drive system and energy feed-
back to the AC system.
• Brake resistors
12.1 Supply concept
Select in the "Select supply concept" dimensioning step a power supply module or a regenerative
power supply module.
• The dimensioning step is only available in the "Dimensioning multi-axis system" application.
9400 power supply module
• Central AC mains connection for a Multi Drive axis interconnection.
• Integrated brake chopper and connection to DC bus busbar system.
• Filters and a brake resistor are to be provided externally if required.
• By the collective use of the mains supply, the mains filter, the brake chop-
per and the DC-bus busbar system, the expenses for material and instal-
lation within a Multi Drive axis interconnection are considerably
reduced.
9400 regenerative power supply module
• Optimally suitable for clock drives as the module is able to provide a mul-
tiple of the rated power for a short time.
• For increasing the supply power, the supply modules can be connected in
parallel.
• For increasing the regenerative power, several regenerative power sup-
ply modules can be connected in parallel.
• Easy mounting and installation through separation of installation back-
plane and electronic module.
• Mains filters can be simply added and connected to the installation back-
plane via the available connecting cables.
i700 power supply module
• Internal brake chopper and brake resistor.
• If required, an external brake resistor can be connected.
• 5-fold overload is permissible for a short time.
• A power supply module can supply up to 10 axis modules.
