CU320-2 Control Units
■
Integration
DRIVE-CLiQ components such as Motor Modules and Active
Line Modules can be connected to a CU320-2 Control Unit.
The number of modules depends on the performance required,
including duty type and additional functions.
The BOP20 Basic Operator Panel can also be snapped onto the
CU320-2 Control Unit during operation for diagnostic purposes.
The CU320-2 Control Unit and other connected components are
commissioned and diagnosed with the STARTER commission-
ing tool.
A CompactFlash card with firmware version V4.4 or higher
is a mandatory requirement
for operation of the
CU320-2 PN Control Unit.
A CompactFlash card with firmware version V4.3 or higher
is a mandatory requirement
for operation of the
CU320-2 DP Control Unit.
