1.5 Rules for wiring with DRIVE-CLiQ
11. Parallel operation of power units in chassis format:
12. For parallel connection of Motor Modules, only one SINAMICS Sensor Module Integrated
13. Switchover between different motors is not permitted for a parallel connection.
14. Mixed operation of Infeed Modules or Motor Modules:
15. Mixed operation of formats:
16. Mixed operation of control types:
17. Mixed operation of control cycles:
18. Operation with Voltage Sensing Module (VSM):
22
– A parallel connection of power units is permissible for vector control and U/f control
but not for servo 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.
– Only just one parallel connection of Motor Modules is permissible. For a parallel
connection, exactly one drive object ("Servo" or "Vector") is created in the topology.
(SMI) 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)
– Chassis Motor Modules and booksize Motor Modules must 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 with 62.5 µs and servo with 125 µs
– Servo with 125 µs and servo with 250 µs
– Vector with 250 µs and vector with 500 µs
– Exactly 1 Voltage Sensing Module (VSM) may be connected to one Line Module.
Exception: If the "Transformer" function module is activated, a second VSM may be
connected.
– A maximum of 2 VSMs may be connected to one Motor Module.
– The VSM must be connected to a free DRIVE-CLiQ socket of the associated Line
Modules/Motor Modules (to support automatic assignment of the VSM).
