Diagnostics

Communication failure when booting or in cyclic operation
If at least one sender does not correctly boot after commissioning or fails in cyclic operation,
then alarm A50005 is output to the other nodes: "Sender was not found on the SINAMICS
Link."
The message contains the number of the faulted node. After you have resolved the fault at
the node involved and the system has identified the node, the system automatically
withdraws the alarm.

– Define the PZD to be sent for the SINAMICS DCM:
DO2 p2051.0 = r0898
DO2 p2051.1 = r0899
DO2 p2051.2 = r52211
DO2 p2051.3 = r52013
– Assign this PZD to the send buffer (p8871) of its own DO:
DO2 p8871.0 = 1 (SINAMICS Link send PZD 0 = DO2 p2051.0)
DO2 p8871.1 = 2 (SINAMICS Link send PZD 1 = DO2 p2051.1)
DO2 p8871.2 = 3 (SINAMICS Link send PZD 2 = DO2 p2051.2)
DO2 p8871.3 = 4 (SINAMICS Link send PZD 3 = DO2 p2051.3)
– This means that you have defined the position of the data in the 16-word telegram of
the drive unit.
– Define that receive buffer 0 should be filled with data from CU320-2:
DO2 p8872.0 = 2
– Define that PZD 1 of CU320-2 should be saved in this buffer:
DO2 p8870.0 = 1
– For the CU320-2, define the PZD to be sent:
DO1 p2051.0 = r21530 (output of the DCC closed-loop control)
– Define that the receive buffer 0 should be filled with data from SINAMICS DCM:
DO1 p8872.0 = 1
DO1 p8872.1 = 1
DO1 p8872.2 = 1
DO1 p8872.3 = 1
– Define that PZD1 of SINAMICS DCM should be saved in this buffer:
DO1 p8870.0 = 1
DO1 p8870.1 = 2
DO1 p8870.2 = 3
DO1 p8870.3 = 4
