Several drives can be accessed via one or more NDBU-95 devices (DDCS branching unit). 8 drives can be connected to each NDBU-95. Up to 16 NDBU-95 devices can be cascaded.
ibaBM-DDCS is connected to the MSTR port of the NDBU-95 with a bidirectional FO cable.

When acquiring parameter in a star topology, ensure that the connected drives are set to “Star” mode. In DriveWindow, the parameter “CH3 HW CONNECTION” in the parameter set “DDCS Control” of each drive has to be checked and set to “STAR”.

Settings at the branching unit NDBU-95
|
Address setting (S1): Address range 76 … 124 (01001100 … 01111100) = 0x4C … 0x7C Note: When NDBU-95 units are cascaded, each unit must have a unique address between 76 and 124. Units with higher addresses must be closer to the ibaBM-DDCS within the cascade. Use only even-numbered addresses. |

Operating mode selection (X13): Adjust to DDCS/DRIVEBUS mode. |
