Description
With option K90, a CU320-2 Control Unit is installed in the Line Modules and Motor Modules
of the drive line-up; the CU320-2 assumes the functions of communication, open-loop
control, and closed-loop control for up to 4 Motor Modules, in addition to 1 Line Module.
The connection to the relevant modules and any additional I/O modules is established via
DRIVE-CLiQ. A standard PROFIBUS interface is available for higher-level communication.
The unit can communicate with other nodes via PROFIBUS or the DRIVE-CLiQ interface,
see SINAMICS Low-Voltage Configuration Manual on the customer DVD supplied with the
device.
Note
CU320-2 Control Unit without performance enhancement
Without performance enhancement, it is generally possible to operate 2 Motor Modules plus
1 Line Module.
Note
Performance expansion 1
The computing capacity required increases in proportion to the number of connected Motor
Modules and system components and in relation to the dynamic response required. The full
computing capacity of the CU320-2 Control Unit is available only on systems with
performance expansion 1.
