Issue 1.11
ibaPDA only supports the acquisition of analog parameter values in 32-bit IEEE-Float
format and digital parameter values.
Important note
Analog parameters in other formats, e. g. DINT, are misrepresented in ibaPDA.
When there is only one drive, ibaBM-DDCS can be connected directly to the CH3 port
(service channel) of the drive. When there are several drives, the communication can be
established using a NDBU-95 in star or ring topology.
8.4.2
Star topology
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.
Important note
When acquiring parameters 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”.
