can be continued but an alarm may occur and proper operation may not be performed.
Refer to this section and remedies for warnings of [GF] and [Others] in the MELSERVO-J4 Servo Amplifier
Instruction Manual (Troubleshooting) to remove the cause of a warning. Use MR Configurator2 to refer to the
cause of warning occurrence.
If [AL. E3 Absolute position counter warning] occurs, always make the home
position setting again. Otherwise, it may cause an unexpected operation.

amplifier and servo motor. If the power of the servo amplifier is switched off/on
during the warnings, allow more than 30 minutes for cooling before resuming
operation.
