Basic principles of SINAMICS Link

A drive unit (with a node number) most frequently comprises a Control Unit with a number of
connected drive objects (DOs). SINAMICS Link allows data to be directly exchanged
between up to 64 CU320-2 PN or CU320 -2 DP Control Units or CUD. The SINAMICS Link
requires the CBE20 additional module. All participating Control Units must be equipped with
a CBE20. Possible applications are, for example:
● Torque distribution for n drives
● Setpoint cascading for n drives
● Load distribution of drives coupled through a material web
● Master/slave function for infeed units
● Links between SINAMICS DC-MASTER and SINAMICS S120
Requirements
The following preconditions must be fulfilled to operate SINAMICS Link:
● r2064[1]: The bus cycle time (T
● r2064[2]: The master cycle time (T
● The current controller cycle must be set to 250 µs or 500 µs. One clock with 400 µs is not
Note
The "SINAMICS Link" function is not available for the Control Unit CU310-2.
Note
SINAMICS Link for chassis format
For the following devices in the chassis format, you must manually set parameter p0115[0] to
250 μs or 500 μs:
• 380 - 480 V 3-phase AC: All devices with rated current In ≥ 605 A
• 500 - 690 V 3-phase AC: All units
