Interconnecting The Receive Buffer - Siemens SINAMICS S120 Commissioning Manual

Commissioning
3.6 Interconnecting process data in the receive and transmit buffers
Note
The excerpts of function diagrams for the receive/transmit buffer, which are shown in the
following sections, illustrate:
- How the process data objects in the receive and transmit buffers are distributed to the
receive and transmit words.
- Which associated target and source parameters for the receive and transmit words have
to be interconnected (highlighted).
Note
The SINAMICS source and target parameters, which are interconnected with the receive and
transmit words, are listed in the "SINAMICS parameter" column in the "Objects in drive
profile DSP 402" table.

Interconnecting the receive buffer

Introduction
In the receive buffer, the following are interconnected for the transmission message frames:
● Control word (PZD 1)
● Set velocity (PZD 2+3)
● Set torque (PZD 4)
Steps
If you for example: are interconnecting the set velocity process data object in the PZD
receive word 2+3 (32 bit), proceed as follows. interconnect the following target and source
parameters:
● SINAMICS target parameter for the set velocity (p1155[0] => 32 bit, see "Objects in drive
