Basic principles of SINAMICS Link

SINAMICS Link allows data to be directly exchanged between several control units (CU320-
2 PN and CU320-2 DP). The participating Control Units must be equipped with the CBE20
supplementary module. Other nodes cannot be integrated into this communication.
Possible applications include, 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
Preconditions
The following preconditions must be fulfilled to operate SINAMICS Link:
● r2064[1]: The bus cycle time (Tdp) must be an integer multiple of p0115[0] (current
● r2064[2]: The master cycle time (Tmapc) must be an integer multiple of p0115[1] (speed
● p0115[0]: The current controller cycle clock must be set to 250 μs or 500 μ; 400 μs is not
Send and receive data
The most frequently used node comprises a drive unit with a Control Unit and a number of
connected drive objects (DOs). A SINAMICS Link telegram has place holders for 16 process
data (PZD). Each PZD is precisely one word long. Slots that are not required are filled with
zeros

SINAMICS Link
Every node can send a telegram with 16 PZD. Each node can receive all telegrams, which
are sent on the bus. A node can select and process up to 16 PZDs from all telegrams. Single
words and double words can be sent and received. Double words require 2 consecutive
PZDS.
