Canopen Functionality Cu305 Can - Siemens SINAMICS S120 Commissioning Manual

Prerequisites for commissioning
2.3 CU305 CAN (SINAMICS S110)
The CU305 CAN is connected to the CANopen bus system via the X126, a 9-pin Sub D
connector. The connector can be used as an input or an output. Unused pins are plated
through.
The following baud rates are supported: 10, 20, 50, 125, 250, 500, 800 kBaud, and 1 Mbaud.

CANopen functionality CU305 CAN

Introduction
The CU305 CAN supports the CANopen transmission types with SDOs (service data
objects) and PDOs (process data objects).
The CU305 CAN also supports free PDO mapping.
The CU305 CAN supports CANopen communication profile DS 301 version 4.0, device
profile DSP 402 (drives and motion control) version 2.0, and indicator profile DR303-3
version 1.0.
For communication monitoring purposes, the CU305 CAN supports node guarding and the
heartbeat protocol (heartbeat producer).
The CU305 CAN features an SDO->parameter channel that can be used to read or write all
the SINAMICS parameters.
The CU305 CAN firmware supports profile velocity mode.
