How do you resolve an E6 alarm? Is this an indication the spindle is bad?

An E6 alarm on the Nakanishi iSpeed3 indicates a loss of speed control sensing inside the motor, possibly due to no speed signal, impact, or torque overload. To resolve it, check for:

1. Signal loss from the speed sensor.
2. Mechanical impact or excessive torque load.
3. Electrical connections and control signals.

An E6 alarm does not necessarily indicate a bad spindle. It may be caused by external issues or sensor failure. Test and inspect before replacing the spindle.
