Overview
CUA32 Control Unit Adapter
The CUA32 Control Unit Adapter converts the PM-IF interface to
a DRIVE-CLiQ interface. The CUA32 Control Unit Adapter is also
equipped with an integral encoder evaluation device which can
be configured for an HTL/TTL or SSI encoder. The CUA32
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 CUA32 Control Unit Adapter must be
the last device in the DRIVE-CLiQ link from the viewpoint of the
Control Unit.
■
Design
The CUA32 Control Unit Adapter features the following
connections and interfaces:
•
1 temperature sensor input for KTY84-130, Pt1000 or PTC
(Pt1000 can be used from firmware V4.7 HF17)
•
3 DRIVE-CLiQ sockets
•
1 connection for the electronics power supply via the 24 V DC
power supply connector
•
1 Safe Stop input
•
1 encoder evaluator for
- Incremental encoder TTL/HTL
- SSI encoder without incremental signals
The status of the CUA32 Control Unit Adapter is indicated via
multi-color LEDs.
