Descriptions of functions
10.4 Communication via SINAMICS Link
4. Define the send data (SINAMICS DCM):
5. Define the receive data (SINAMICS DCM):
6. Define the send data (CU320-2):
7. Define the receive data (CU320-2):
8. Carry out a RAM to ROM and then a power cycle at all components to activate the
388
– 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
