The following is a short description – indicating the cause and potential solutions for the Melservo AL.E9 Error.
If the main circuit power is ON, and this error still appears, then the MR-J2S Servo drive – then the drive is damaged and needs to be replaced.
In short – the AL.E9 has two possible causes:
- First powering 24V of the signal (like SON..) and then 230Vac Power supply.
Solution: Be sure you first power the 230Vac Power supply and then 24V.
2. If #1 does not address the error – then the Servo amplifier is faulty\damaged.
Solution: Replace the Melservo amplifier (migration towards MR-J4).
