Overview
CUA31 Control Unit Adapter
The CUA31 Control Unit Adapter converts the PM-IF interface to
a DRIVE-CLiQ interface. The CUA31 Control Unit Adapter allows
Power Modules in blocksize format to operate on a Control Unit,
e.g. as a single axis next to a multi-axis drive. In this case, the
CUA31 Control Unit Adapter must be the last device in the
DRIVE-CLiQ link from the viewpoint of the Control Unit.
■
Design
The CUA31 Control Unit Adapter features the following
connections and interfaces:
•
1 temperature sensor input for KTY84-130, Pt1000 or PTC

•
3 DRIVE-CLiQ sockets
•
1 connection for the electronics power supply via the 24 V DC
supply connector
•
1 Safe Stop input
The status of the CUA31 Control Unit Adapter is indicated via
