Note
For double words, two PZD must be read in succession. Read a 32-bit setpoint that is at
PZD 2+PZD 3 of the telegram from node 2, and map this to PZD 2+PZD 3 of node 1:
p8872[1] = 2, p8870[1] = 2, p8872[2] = 2, p8870[2] = 3
Activation
To activate SINAMICS Link connections, perform a POWER ON for all nodes. The
assignments of p2051[x]/2061[2x] and the links of the read parameters r2050[x]/2060[2x]
can be changed without a POWER ON.
10.6.4 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:
– 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
● Send data from CU320-2 to SINAMICS DCM:
– r21530 CO: Output, PI controller (1 PZD), in the example, PZD 1
Procedure
1. For all nodes, set the SINAMICS Link mode: DO1 p8835 = 3
2. Assign node numbers for the two devices:
– SINAMICS DCM: DO1 p8836 = 1
– CU320-2: DO1 p8836 = 2
