Operation
6.10 Communication via SINAMICS Link
Activation
To activate SINAMICS Link connections, perform a POWER ON for all nodes. The
assignments of p2051[x]/2061[x] and the links of the read parameters r2050[x]/2060[x] can
be changed without a POWER ON.
Settings for cabinet units with rated pulse frequency 1.25 kHz
For the following cabinet units with a rated pulse frequency of 1.25 kHz, in addition
parameter p0115[0] must be set from 400 µs to 250 µs or 500 µs:
● 3 AC 380 to 480 V: All cabinet units with rated output current I
● 3 AC 500 to 600 V: All cabinet units
● 3 AC 660 to 690 V: All cabinet units
Generally, the following conditions must be met:
1. r2064[1] bus cycle time (Tdp) must be an integer multiple of p0115[0] (current controller
2. r2064[2] master cycle time (Tmapc) must be an integer multiple of p0115[1] (speed

Example

Task
Configure SINAMICS Link for two nodes and transfer the following values:
● Send data from node 1 to node 2
● Send data from node 2 to node 1
Procedure
1. For all nodes, set p0009 = 1 to change the device configuration.
2. For all nodes, for the CBE20, set the SINAMICS Link mode:
3. Assign the node numbers for the devices involved:
