Drive System
ABB Standard (Std) and Engineered (Eng) Drives can be connected to AC 800M
through any of the following:
• The optical ModuleBus
• CI801 and PROFIBUS DP
• NPBA-12, RPBA-01, or FPBA-01 PROFIBUS DP Adaptor modules along
with CI854
• RETA-02 or FENA-01/-11 Ethernet Adapter modules along with CI871
(PROFINET IO)
•CI858 DriveBus Interface.
ModuleBus
In single CPU configuration, ABB Drives can be connected to the processor unit via
the optical ModuleBus. See Figure 59 on page 171. The number of ABB Drives
which can be connected to the optical ModuleBus, can be described by the
following equation:
(No. of ABB Drives) < 84 - (12 x (No. of TB820s))
that is, each Drive uses one ModuleBus cluster.
PROFIBUS DP and CI801
In single and redundant CPU configuration, ABB Drives can be connected via
PROFIBUS DP and CI801. See Figure 59 on page 171. Only Standard Drives can
be connected to CI801. Fourteen (14) Standard Drives can be connected to each
CI801 if there are no I/O units connected. For the number of Drives that can be
connected to the same CI801, when both I/O units (TB820) and Standard Drives are
connected, refer to documentation about FCI for PROFIBUS DP.
For more information about ABB Drives and its types (Std and Eng) refer to
S800 I/O documentation.
For information about Branching Unit (Figure 59 on page 171) see ABB Drive
System documentation.
ABB drives can also be connected via PROFIBUS DP (CI854/CI854A), with direct
connection to PROFIBUS DP slave modules NPBA-12, RPBA-01, and FPBA-01.
