Connecting Inverter To Can Bus; Setting The Node Id And Baud Rate - Siemens Sinamics G120P Operating Instructions Manual

Procedure
Proceed as follows to commission the CANopen interface:
1. Connecting inverter to CAN bus (Page 289)
2. Set the node ID, baud rate and the monitoring of the communication.
Also see "Setting the node ID and baud rate (Page 289)" as well as "Setting the
monitoring of the communication (Page 290)"
3. Interconnect additional process data
Set p8744 = 2. You can now interconnect additional process data.
See also "Free PDO mapping (Page 271)"
4. Signal interconnection of the links created in free PDO mapping.
See also Interconnect objects from the receive and transmit buffers (Page 274).
5. Exit commissioning
Select the "Operational" status in the "Network management" tab in the "Control
Unit/Communication/CAN" STARTER screen form and exit the commissioning.
More information about configuring the communication is provided in Sections Object
directories (Page 276) and CANopen functions of the converter (Page 257).
6.9.3.1

Connecting inverter to CAN bus

Connect the converter 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 converter
forms the first or last slave in the CANopen network, then you must switch-in the bus-
terminating resistor.
For additional information on the SUB-D pin connector and on the bus-terminating resistor,
please refer to Section CU230P-2 CAN Control Unit (option K99) (Page 93).
6.9.3.2

Setting the node ID and baud rate

Setting the node ID
You set the node ID of the inverter using the ad-
dress switches on the Control Unit, using parame-
ter p8620 or in STARTER.
Valid address range:
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 (facto-
ry setting: 126) will not be able to be changed.
The positions of the address switches are de-
scribed in Section: CU230P-2 CAN Control Unit
(option K99) (Page 93).
