Operation
6.10 Communication via SINAMICS Link
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 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
clock cycle).
2. r2064[2] master cycle time (Tmapc) must be an integer multiple of p0115[1] (speed
controller cycle).

Example
Task
Configure SINAMICS Link for two nodes and transfer the following values:
● Send data from node 1 to node 2
– r0898 CO/BO: Control word, sequence control, drive 1 (1 PZD), in the example PZD 1
– r0079 CO: Total torque setpoint (2 PZD), in the example PZD 2
– r0021 CO: Smoothed actual speed (2 PZD), in the example PZD 3
● Send data from node 2 to node 1
– r0899 CO/BO: Status word, sequence control, drive 2 (1 PZD), in the example PZD 1
● IF1 is used for SINAMICS Link.
Procedure
1. For all nodes, set p0009 = 1 to change the device configuration.
2. For all CBE20 nodes, set the "SINAMICS Link" mode using p8835 = 3.
3. Limit the maximum number of nodes for all nodes with p8811 = 8. By setting p8811,
parameter p8812[1] is preassigned, and parameter p8836, if necessary, is corrected.
4. Assign the node numbers for the devices involved:
– Node 1 (≙ device 1): p8836 = 1
– Node 2 (≙ device 2): p8836 = 2
5. Set all CBE20 to the isochronous mode by setting p8812[0] = 1.
