A.4.2
System rules
A maximum of 24 drive objects (DOs) can be connected to one Control Unit.
Control Units
● The CU320-2 Control Unit is a multi-axis control module for operating Infeed Modules and
Motor Modules in the booksize format. Sensor Modules can also be connected.
Motor Modules/control modes
For the CU320-2 Control Unit the following applies:
● The CU320-2 Control Unit is a multi-axis control module for operating Motor Modules in
the booksize format.
● For multi-axis modules, each axis counts individually (one Double Motor Module = two
Motor Modules).
● Mixed operation of control types:
The following are permitted:
– Mixed operation of servo control and V/f control.
The following applies when connecting Motor Modules in parallel:
● It is not permissible to connect Motor Modules in parallel.
Line Modules
For the CU320-2 Control Unit the following applies:
● Only one drive object of the Smart Line Module (SLM), Basic Line Module (BLM) and
Active Line Module (ALM) types is permitted in each case.
● Mixed operation of an Active Line Module with a Smart Line Module (SLM) or with a Basic
Line Module (BLM) is not permitted.
● Mixed operation of a drive object of the Smart Line Module (SLM) type with a drive object
of the Basic Line Module (BLM) type is permitted.
● Two further Voltage Sensing Modules can be operated with the "network transformer"
function module for Active Line Modules (ALM).
The following applies to parallel connection of Line Modules:
● Parallel connection is permitted for Infeed Modules in the chassis format and for Active
Line Modules (ALM) from the 120 kW performance class for the booksize format.
● A maximum of four Infeed Modules are permitted within a parallel connection.
● In booksize format, a maximum of two Active Line Modules (ALM) from the 120 kW
performance class are permitted within a parallel connection.
● The operation of Infeed Modules with different performance values is not permitted within
a parallel connection.
