 Problem specific troubleshooting

3.1​ I wanted to use the Auto-script control on my Series 1780 but it kept telling me there was a syntax error and there was no response from the motor.

If you find no response from the ESC when you click to start an automatic test, it is due that the Series 1780 supports coaxial. Therefore, you must tell the difference between ESC A and B in the auto-script.

  • Exit the script running mode and return to edit the script.
  • Look for the following scripts by manual searching or Ctrl +F of “rcb.output”, please note that there can be multiple locations using this definition:
  • rcb.output.set("esc",minVal)
  • rcb.output.ramp("esc", from, to, duration, done);
  • rcb.output.steps("esc", from, to, steps, stepFct);
  • Replace the script by for the side A:
  • rcb.output.set("escA",minVal)
  • rcb.output.ramp("escA", from, to, duration, done);
  • rcb.output.steps("escA", from, to, steps, stepFct);

Example coaxial script

  • In case that you are using the Coaxial version, you may also define escB in a similar way. You may visit this link for an example coaxial control script:

  • We also strongly recommend you to read the API library before making any further changes:
