KEBA KeDrive D3-DP 30x supply units

The power supply

The power for the multi-axis system comes from a central supply unit in steps from 10 kW to 140 kW. While for the supply units

BG1+2 (10 - 22 kW) an integrated power supply unit (SMPS) optionally provides the 24 V/480 W auxiliary supply, for the supply

units BG3+4 (45 - 140 kW) an external 24 V supply is required. This 24 V auxiliary supply can be provided by an existing 24 V power

supply unit in the machine.

Axis controllers are arranged on the right of the supply unit on a rail system. The control modules D3-DU 3xx are mounted on the

left. The connection of the axis controllers to the DC link supply and the 24 V DC auxiliary voltage is realised without wiring effort

using the integrated busbar system. Only the 24 V DC auxiliary voltage is transmitted to the controller. Digital outputs indicate the

actual status.

The supply unit supplies the energy for the axis controllers. Configuration, diagnostics and status information are realised via the first

axis on the first axis controller in the drive group. A maximum of 9 modules are allowed to be connected and operated in the axis

group (D3-DP, D3-DC, D3-DA, D3-DE...).

Safety technology

Test outputs provide OSSD output signals. The OSSD output signals are used for the short-circuit and cross-circuit test on the

wiring for the safe, digital inputs on the axis side.

Device protection/mains contactor

A relay output is provided with which it is possible to control an external mains contactor via the controller D3-DU 3xx integrated into

the system.
