Troubleshooting Remedies for warnings
8 - 28
8.5 Remedies for warnings
If AL. E6, AL. E7, AL. E9, AL. EA, or AL. EB occurs, the servo-off status is established. If any other warning
occurs, operation can be continued but an alarm may take place or proper operation may not be
performed.
Remove the cause of warning according to this chapter. Use MR Configurator2 to refer to a factor of
warning occurrence.
8.6 Trouble which does not trigger alarm/warning
For possible causes which do not trigger alarm or warning refer to “MELSERVO J4 Servo Amplifier
Instruction Manual (Troubleshooting)”.
Remove each cause referring to the respective sections of the manuals.
b
WARNING:
If AL. E3 (Absolute position counter warning) occurs, always make home position setting again.
Otherwise, it may cause an unexpected operation.
NOTES When any of the following warnings has occurred, do not cycle the power of the servo amplifier
repeatedly to restart. Doing so will cause a malfunction of the servo amplifier and the servo motor.
If the power of the servo amplifier is switched off/on during the alarms, allow more than 30 min-
utes for cooling before resuming operation.
– AL. 91 (Servo amplifier overheat warning)
– AL. E0 (Excessive regeneration warning)
– AL. E1 (Overload warning 1)
– AL. E2 (Servo motor overheat warning)
– AL. EC (Overload warning 2)
Warnings are not recorded in the alarm history.
