Alarm Description
The encoder output errors or the
output pulse exceeds hardware
tolerance.
Encoder temperature exceeds the
warning level. (But it is still within the
protective range.)
When the output current from servo
drive exceeds the setting level,
ALE083 will be triggered to protect
IGBT. This could avoid IGBT to be
burned out because of the excessive
current.
EEPROM has not been reset after
upgrading the firmware. The fault
can be cleared when firstly set P2-08
to 30. Then set P2-08 to 28. And
re-power on the drive.
