When COMMODE0 is in effect:
⚫ Enable serial RS232/USB communication.
⚫ Disable EtherCAT/CANopen communication.
⚫ PROFINET communication accepts parameter reading and writing, real-time
data reading, and cannot be enabled.
⚫ Reference commands are received only through the serial/pulse/analog port.
⚫ Drive can be fully controlled through operation panel and ServoStudio 2
(enabling, motor action, parameter modification).
Note: The operation panel and ServoStudio 2 are not given priority.
Only applicable to CDHD2SAF, EC and EB models.
When COMMODE1 is in effect:
⚫ Enable EtherCAT/CANopen communication.
⚫ Serial RS232/USB communication can be used as a tool for monitoring and
modifying parameters.
⚫ Reference commands can be received through the serial/pulse/analog port.
⚫ Drive can be fully controlled by the field bus device.
⚫ The drive or motor cannot be enabled through ServoStudio 2 or the operation
panel
Note:Certain functions must be performed through ServoStudio 2 or the operation
panel. These functions are limited to parameters that do not interfere with
the operation of the fieldbus. If you want to set parameters that will
interfere with the operation of the fieldbus, the drive will issue an error code
on the digital display and/or issue an error message on ServoStudio 2.
Set the bit rate of serial communication between the drive and the host.
Set the bit rate of CAN bus communication between the drive and the host.
You can establish communication between the host and the drive through the ServoStudio2
communication screen. In addition, the first step in the Motor Setup wizard is to configure
communication between the host and the drive.
6.3.1 Serial baud rate
The default baud rate of CDHD2S is 115200. If the settings are changed and saved in the non-
volatile drive memory, the saved baud rate will be used when the drive is powered on.
For example, when there is a connection problem, you can try to use a lower baud rate.
Procedure: Modify serial baud rate
To modify the baud rate settings, changes must be made both in the drive and in the
ServoStudio2 software.
1. Changing the baud rate in the drive:
◼ Enter the terminal screen.
◼ Issue a command to change the baud rate; for example: BAUDRATE19200
◼ Press enter.
When the enter key is pressed, communication is instantly lost and ServoStudio2 goes offline.
2. Changing the baud rate in ServoStudio2.
