Measure input voltage lines under load. Check incoming supply fuses and circuit breakers. / Err.06

| Alarm Code | Error Description | Typical Causes & Solutions | | :--- | :--- | :--- | | | Low Voltage | - Input power phase loss or low voltage. - Main circuit capacitor deterioration. | | AL-02 | Overvoltage | - Power supply voltage is too high. - Regenerative braking resistor is open or disconnected. | | AL-03 | Overload | - Motor shaft is locked or load is excessive. - Motor output wiring (U, V, W) is incorrect. | | AL-04 | Overcurrent | - Drive output short-circuit or ground fault. - Power transistor (IGBT) module failure. | | AL-05 | Encoder ABZ Signal Error | - Faulty encoder wiring or connector. - Encoder internal failure. | | AL-10 | Motor Overcurrent | - Incorrect motor parameter settings. - Load inertia is too high for the selected gain settings. | | AL-11 | Position Error Excess | - Position command pulse frequency is too high. - Motor is unable to follow command due to stall or gain settings. | | AL-12 | Motor Overspeed | - Speed command input voltage is too high. - Speed loop gain (Pn101) is set too high. | | AL-15 | Drive Overheating | - Ambient temperature exceeds specification. - Cooling fan failure or blocked ventilation. | esda servo motor manual
