FAQ

  1. Troubleshooting The motor does not respond to communication.

    Please check the following:


    1. Verify the ID (Default: ID 0 for 12Lf, ID 1 for 17Lf).
    2. Check if the Baudrate has been changed.
    3. Ensure RS-485/TTL wiring (D+, D-) is not swapped.
    4. Try the Recovery function in Total Manager.

  2. Troubleshooting The motor jitters or hunts at a specific position.

    This happens when the motor cannot stabilize at the target position. It may occur due to increased mechanical backlash over time combined with external forces.

    1. Increase the Compliance Margin (End Margin) by 1~2 steps.
    2. Adjust the PID gains to lower responsiveness.
    3. Check if the load is too high or the voltage is unstable.

  3. Troubleshooting The Red LED blinks, and the motor stops. (Overload Error)

    The Overload Protection has been triggered.

    1. Check if the Duty Cycle exceeded 50% (or ran continuously for over 30 seconds). This is the most common cause. Increase the rest time.
    2. Check for mechanical interference or jamming.
    3. Ensure the load is within the Rated Load specification.
    4. Restarting the power or sending a ‘Restart’ command will recover it, but the cause must be eliminated to prevent recurrence.

  4. Troubleshooting The Red LED stays on, and the motor doesn’t work. (Voltage Error)

    This indicates an input voltage issue. Ensure the voltage
    is not over 13V (Overvoltage) or under 7.4V (Undervoltage). Be
    careful of voltage spikes when batteries are fully charged or voltage drops
    during operation.
