CUA31 Control Unit Adapter
■
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 (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)
The status of the CUA31 Control Unit Adapter is indicated via a
multi-color LED.
■
Integration
The CUA31 Control Unit Adapter is snapped onto the Power
Module in blocksize format and communicates with the
CU320-2 Control Unit, an NCU 7.x of the SINUMERIK by
means of a DRIVE-CLiQ link.
The CUA31 Control Unit Adapter's power is supplied by the
Power Module via the PM-IF interface. If the CUA31 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 CUA31 Control Unit Adapter.
