Connecting Inverter To Can Bus; Setting The Node Id And Baud Rate - Siemens SINAMICS G110M Function Manual

6.7.1

Connecting inverter to CAN bus

Connect the inverter to the fieldbus via the 9-pin SUB-D pin connector.
The connections of this pin connector are short-circuit proof and isolated. If the inverter
forms the first or last slave in the CANopen network, then you must switch-in the bus-
terminating resistor.
For additional information, refer to the operating instructions of the Control Unit.
6.7.2

Setting the node ID and baud rate

Node ID
Valid value range: 1 ... 127
You have the following options for setting the node ID:
● Using the address switch on the Control Unit:
Figure 6-11
The address switch has priority over the other settings.
● Using Startdrive or an operator panel via parameter p8620 (default setting: p8620 = 126)
It is only possible to change p8620 if the address 0 is set in the address switch.
If you are working with Startdrive, back up the settings so they are not lost if the power
fails.
The position of the address switch is available in the operating instructions for the inverter.
Setting the baud rate
You can set the baud rate using parameter p8622. If you are working with Startdrive, back
up the settings so they are not lost if the power fails.
Setting range: 10 kbit/s ... 1 Mbit/s. The maximum permissible cable length for 1 Mbit/s is
40 m.
