General information
Availability of option
This option is available for the following S120 Cabinet Modules:
● Basic Line Modules
● Smart Line Modules
● Active Line Modules
● Booksize Cabinet Kits
● Motor Modules in chassis format
Description
With option K90, a CU320-2 DP Control Unit is installed in the Line Modules and Motor
Modules of the drive assembly; this 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 participants via PROFIBUS or the DRIVE-CLiQ
interface, see SINAMICS Low-Voltage Engineering 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 enhancement
The computing capacity required increases in proporti
on 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 with performance
enhancement.
