Control Unit Adapter CUA31

8.5.1

Description

The CUA31 Control Unit Adapter is used to connect a Power Module blocksize to an existing
DC/AC group with a higher-level control module, e.g. a CU320-2. Since the closed-loop
control is realized externally, for operation, a SINAMICS, SIMOTION, or SINUMERIK closed-
loop control is always required for several axes.
The Control Unit Adapter CUA31 has the following interfaces (ports):
