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:  [font=游ゴシック]Data transmission failure (error code = -1)[/font]

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?
