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

Setting the node ID
You set the node ID of the inverter using the address
switches on the Control Unit, using parameter p8620
or in STARTER.
Valid address range: 1 ... 127
If you have specified a valid node ID using the
address switches, this node ID will always be the one
that takes effect, and parameter p8620 (factory set-
ting: 0) will not be able to be changed.
The position of the address switches can be found in
the operating instructions of the Control Unit in the
section "Overview of interfaces".
Set the address using one of the subsequently listed options:
● using the address switches
● with an operator panel using p8620
● in STARTER using screen form "Control Unit/Communication/Fieldbus", or using the
expert list with p8620
After you have changed the address in STARTER, carry out a RAM to ROM (
Set the baud rate
You set the baud rate using parameter p8622 or in the STARTER screen form
"Control Unit/Communication/CAN" under the CAN interface tab. If you are working with
STARTER, backup the setting using
Setting range: 10 kbit/s ... 1 Mbit/s. The maximum permissible cable length for 1 Mbit/s is
40 m.
