CUA32 Control Unit Adapter
■
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 (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 standstill input (enable pulses)
•
1 encoder evaluator for
- TTL/HTL incremental encoder
- SSI encoder without incremental signals
The status of the CUA32 Control Unit Adapter is indicated via a
multi-color LED.
■
Integration
The CUA32 Control Unit Adapter is snapped onto the Power
Module in blocksize format and communicates with a
CU320-2 Control Unit or a SINUMERIK NCU 7.x via a
DRIVE-CLiQ connection.
The CUA32 Control Unit Adapter's power is supplied by the
Power Module via the PM-IF interface. If the CUA32 Control Unit
Adapter needs to communicate when the Power Module is
switched off, it must be supplied with 24 V DC from an external
source.
Other DRIVE-CLiQ devices such as Sensor Modules or Terminal
Modules can be connected to the CUA32 Control Unit Adapter.
