Control Unit
The CU320 Control Unit is the central control module of the drive's open-loop and closed-loop
control system. The connections are wired internally to the customer terminal block.
3.7.2
Power Stack Adapter
The Power Stack Adapter (PSA) acts as the physical interface between the power unit and the
open-loop/closed-loop controller. This is where the galvanic isolation (electrical coupling via
light) between the power unit and the open-loop controller takes place. Data is exchanged
between the Power Stack Adapter and the Control Unit via the DRIVE-CLiQ high-speed serial
communication interface.
