官方故障排除步驟
Cause: This alarm means that the contacts of the magnetic contactor have stuck together. The alarm condition occurs if the magnetic contactor is already on when an attempt is made to turn it on. The alarm condition is detected between the time the contact sticking occurs, and the time an attempt is made to turn it on. Remedy: 1. Check the magnetic contactor, and replace it if necessary. 2. If the contacts of the magnetic contactor have stuck to each other, turn off the circuit breaker. If the power is switched off without turning off the circuit breaker, the servo amplifier might get damaged, because the stuck contacts keep 3-phase 200 VAC applied to the servo amplifier. 3. Replace the E-Stop unit. 4. Replace the servo amplifier.
