Example

Task
Configure the speed control of a SINAMICS DCM on a CU320-2 to increase the
computational performance when using SINAMICS Link and DCC.
● Send data from SINAMICS DCM to CU320-2:
● Send data from CU320-2 to SINAMICS DCM:
Procedure
1. For all nodes, set the SINAMICS Link mode: DO1 p8835 = 3
2. Assign node numbers for the two devices:
3. Insert the DCC plan for the speed control at the CU320-2:

– r0898 CO/BO: Control word SINAMICS DCM (1 PZD), in the example PZD 1
– r0899 CO/BO: Status word SINAMICS DCM (1 PZD), in the example PZD 2
– r52211 CO: Fixed setpoint output to AOP30 (1 PZD), in the example PZD3
– r52013 CO: Analog input, main actual value (1 PZD), in the example, PZD4
– r21530 CO: Output, PI controller (1 PZD), in the example, PZD 1
– SINAMICS DCM: DO1 p8836 = 1
– CU320-2: DO1 p8836 = 2
– Ensure that the technology package is available on the CU320-2.
– Create the DCC chart and generate the following chart
The values set in this example for LU, LL, TV, TD of the ramp-function generator and LU,
LL, KP, TN of the PI controller must be appropriately adapted. The inputs and outputs of
the DCC blocks must be correspondingly defined as BICO and interconnected with the
corresponding parameters according to the diagram.
