6.5.1

Description

The CUA32 Control Unit Adapter combined with a modular power unit is used to extend an
existing DC/AC drive line-up e.g. with CU320 by one drive. It also provides an encoder
interface (HTL / TTL / SSI).
The closed-loop control is externally implemented. This is the reason that a SINAMICS,
SIMOTION or SINUMERIK closed-loop control is always required for operation.
The maximum DRIVE-CLiQ cable length is 100 m.
The CUA32 Control Unit Adapter has the following interfaces (ports):
