Dear RoboDK,
I attempted to retrieve the robot's position while connected to an external axis, but encountered the attached error. Could you please help me identify the cause of this issue?

Error message: Data transmission failure (error code = -1)

Thank you for your support

Did you synchronize your external axes with the robot arm?

Did you provide the correct pulses/degree ratio for the arm and also the external axis?

Can you share the RoboDK project file?

Dear Albert,
Thank you for your support.
I'm sending the RoboDK file.
Please confirm.

Manami.

I understand you have a 6-axis robot arm synchronized with 1 axis rail. You may need to properly configure the motion group of your external axes.

When you start the driver you can find additional configuration parameters for your driver in an INI file located in your AppData folder:
C:/Users/username/AppData/Roaming/RoboDK-Drivers/MotomanHSE.exe.ini

More specifically, I recommend you to change these settings:

Code:

Debug_Print=false <- Set it to true for more debug information
AXIS_EX_CONTROL_GROUP=1 <- you may need to set it to 2
AXIS_EX_CONTROL_IS_BASE=false
ROBOT_CONTROL_GROUP=1
