Baud Rate and Node ID Selection

The drives factory settings are Baud Rate = 500 Kbit and NodeID = 1. The following steps outline how to change the default settings in Kollmorgen Studio:

  1. Open Kollmorgen Studio. The software will open to the main window.

  2. In the main window, click Change in the Drive Info & Communication window to open the Setup Communication Interface window:


  1. Click Find. The Network Scan window will pop-up.

  2. Click Start:

  1. If the drive has been detected, its system code will be added to the list box.


  2. Select the device and click Config. The Configure Device window will appear:


  3. Change the Node ID and Baud Rate settings as desired and click Store.

  4. The new settings will be used at the next drive's switch on.

TheBaud_Rate (4000.8H) and Node_ID (4000.7H) can be changed writing directly in the objects. To do so, follow these instructions:

Node ID

  1. Using SDO service, write 2 bytes in the Node_ID (4000.7H).

  2. Keeping the high byte equal to 0xAA.

  3. Set the low byte equal to the new ID.

    • For example, to set the Node ID = 5 write 0xAA05.

Baud Rate

  1. Using SDO service, write 2 bytes in the Baud_Rate (4000.8H),

  2. Keeping the high byte equal to 0x55.

  3. Set the low byte equal to the new baud rate according to the following table:

Value Baud Rate

0

1M

1

500K

2

250K

3

125K

For example, to set the baud rate = 500K write 0x5501.

After having written the new value, it is necessary to wait about 1 second to permit to the system to store the new values in NVRAM.

The new baud rate and node ID will be effective at the next drive switch on.
