1.5 Rules for wiring with DRIVE-CLiQ
● Parallel operation of power units in chassis format:
● For a parallel connection of Motor Modules, only one motor with integrated DRIVE-CLiQ
● Switchover between different motors is not permitted for a parallel connection.
● Mixed operation of Infeed Modules or Motor Modules:
● Mixed operation of formats:
● Mixed operation of control types:
● Mixed operation of control cycles:
– Vector control with 250 µs and vector control with 500 µs
● Operation with Voltage Sensing Module (VSM):
28
– A parallel connection of Infeed Modules as well as Motor Modules is only permitted for
vector control or for V/f control.
– A maximum of 4 Infeed Modules are permissible within a parallel connection.
– A maximum of 4 Motor Modules are permissible within a parallel connection.
– Precisely one parallel connection of Motor Modules is permitted. For a parallel
connection, precisely one drive object is created in the topology.
interface (SINAMICS Sensor Module Integrated) is permitted for each Motor Module.
– The operation of Infeed Modules or Motor Modules with different performance values
is not permitted within a parallel connection.
– For Line Modules in chassis format, two parallel connections are permissible for mixed
operation of Smart Line Modules and Basic Line Modules.
– The following combinations of Line Modules are not permissible:
Active Line Module (ALM) with Basic Line Module (BLM)
Active Line Module (ALM) with Smart Line Module (SLM)
– Combining small power units (400V; >250kW) and large power units (500 - 690V) to a
DriveCLiQ line results in current derating as a result of the pulse frequency adaptation.
Chassis Motor Modules and booksize Motor Modules must therefore be connected to
separate DRIVE-CLiQ lines.
– Mixed operation of servo control and vector control is not permissible.
– Mixed operation of servo control and U/f control is permissible.
– Mixed operation of vector control and U/f control is permissible.
The following combinations are permissible:
– Servo control with 62.5 µs and servo control with 125 µs
– Servo control with 125 µs and servo control with 250 µs
– If the function module for line infeed is activated, then a second or third Voltage
Sensing Module (VSM) can be connected to a Line Module.
– The VSM must be connected to a free DRIVE-CLiQ socket of the associated Line
Modules or Motor Modules (to support automatic assignment of the VSM).
