Drive System
ABB Standard (Std) and Engineered (Eng) Drives can be connected to AC 800M
via the optical ModuleBus or via PROFIBUS DP and CI830.
ModuleBus
In single CPU configuration, ABB Drives can be connected to the processor unit via
the optical ModuleBus. See Figure 30 on page 101. 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))
PROFIBUS DP and CI830
In single and redundant CPU configuration, ABB Drives can be connected via
PROFIBUS DP and CI830. See Figure 30 on page 101. Only Standard Drives can
be connected to CI830. Fourteen (14) Standard Drives can be connected to each
CI830 if there are no I/O units connected. For the number of Drives that can be
connected to the same CI830, when both I/O units (TB820) and Standard Drives are
connected, refer to documentation about FCI for PROFIBUS DP. See Related
Documentation on page 17.
For more information about ABB Drives and its types (Std and Eng) refer to
S800 I/O documentation, see Related Documentation on page 17.

System documentation.
