ASDA-A2
AL231：The setting of monitor item of PR#8 is out of the range
Causes
The monitor item of the
command source
exceeds the range.
AL235：PR command overflows
Causes
PR command error
AL237：Indexing coordinate is undefined
Causes
When executing indexing
function, if the index
positioning command is
directly executing before
defining the start point of
index coordinate, the
alarm will therefore occur.
10-32
Checking Method
Writing parameter via PR
procedure: The monitor item
number of command source
exceeds the range.
Checking Method
Incremental type:
PR mode continuously operates in
one direction and causes feedback
register (FB_PUU) overflows. And
the coordinate system cannot reflect
the correct position. If issuing the
absolute positioning command at
this time, the error will occur.
Absolute type:
The error occurs in following
situations:
1. Feedback register (FB_PUU)
overflows
2. After P1-01.Z is modified, the
system neither returns to the
original point nor conducts
homing procedure.
3. It does not conduct homing
procedure after the E-gear ratio
is modified (P1-44 and P1-45).
4. Returning to the original point is
triggered and the homing
procedure is not complete.
5. When AL060 and AL062 occur,
please use the scope to check if
the feedback position has
overflowed. Check steps 1- 4
above and perform the homing
procedure.
Checking Method
Indexing coordinate is undefined
and then execute index positioning
command.

Corrective Actions
DI.Alm Reset or write 0 into P0-01
Corrective Actions
Conduct homing procedure.
Corrective Actions
1. Before executing indexing
function, please conduct
homing first so as to avoid this
alarm.
2. When the alarm occurs, please
use DI:Alm Reset or write 0 into
P0-01 to clear the alarm.
3. The alarm can be cleared when
it is Servo ON.
