feedback position has overflowed. Check steps 1—4 above and perform
the homing procedure.
How to clear the
alarm?
Perform homing procedure.
AL237 Indexing coordinate is undefined
Trigger condition
and causes
Condition: using the indexing function and execute positioning command
before defining the start point of the indexing coordinate.
Cause: The servo drive cannot identify this coordinate system.
Checking methods
and corrective
actions
Check if the indexing coordinate has been defined:
1. Perform the homing procedure before using the indexing function.
2. After alarm occurs, use DI.ARST or set P0.001 to 0 to clear the alarm.
3. This alarm is also cleared when you power on the servo.
How to clear the
alarm?
DI.ARST or set P0.001 to 0.
AL283 Software positive limit
Trigger condition
and causes
Condition: the target position specified by the command exceeds the
software positive limit.
Cause: reaching the software positive limit.
Checking methods
and corrective
actions
When you enable the software positive limit function, this alarm is
determined by the command instead of by the feedback position. The alarm
may occur while the actual position is still within the allowable range. The
software positive limit is determined by the Position command instead of the
actual feedback position because the command is sent before the feedback
is received. That is, the actual position may have not reached the limit when
the limit protection has been triggered. To fix this, you can set a proper
deceleration time to satisfy the application requirement. Please see
description for P5.003.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset).
AL285 Software negative limit
Trigger condition
and causes
Condition: target position specified by the command is less than the
software negative limit.
Cause: the software negative limit is triggered.
Checking methods
and corrective
actions
The software negative limit is determined by the Position command instead
of the actual feedback position because the command is sent before the
feedback is received. That is, the actual position may have not reached the
limit when the limit protection has been triggered. To fix this, you can set a
