Some drivers report ALE09 to indicate that the servo motor is overloaded, at this time should check whether the load is too heavy, or whether the motor wiring is not strong or disconnected.
Some drivers report that ALE09 is a servo motor encoder signal feedback problem. In general, there is no gravity percussion encoder, it will not break. Therefore, it is important to check whether the connection between the encoder output and the driver is faulty. Many manufacturers' encoders are connected to the driver's signal port through a dedicated connector. Therefore, you should check whether the connector is inserted firmly, or whether the contact is good. Also, see if the signal plug on the driver is loose.
A: What can I do if the server is faulty al 009?
The causes of AL009 alarm include: insufficient motor output due to lack of phase of UVW connection, low gain setting, low torque limit, high command frequency or excessive electronic gear ratio leading to the motor reaching the maximum speed limit, motor encoder failure, etc., which need to be analyzed in detail.
Servo driver alarm ALE04: When the AB series servo driver is equipped with ECMA motor, the power mismatch will alarm ALE04. Except in this case, ALE04 will alarm ALE04 as soon as it is powered on, which is the motor encoder fault.
Frequency converter fault code AL009 indicates that the frequency converter is overloaded.

Fault causes: the actual load is too heavy, the flow is too large, and the check valve is not strict.

Solution: Verify whether the inverter and the motor match.
