[Md.9] Axis in which the error occurred
This area stores the axis number in which the error is detected.
■
Buffer memory address
For the buffer memory address of this area, refer to the following.
■
Configuration of error history
Information on errors is stored in the error history of pointer 0 to 15. The following figure shows the configuration of the error
history.
When the number of the error history exceeds 15, the newer error information is stored from pointer 0 again and the previous
error information is overwritten.
[Md.10] Error No.
This area stores the error number. Monitor the value in hexadecimal.

Stores a pointer number that comes next to the number
assigned to the latest error history record.
Buffer memory
address
⋅
Pointer number 0 = Buffer memory addresses 1293 to 1296, 1456
Pointer number 1 = Buffer memory addresses 1297 to 1300, 1457
Pointer number 2 = Buffer memory addresses 1301 to 1304, 1458
Pointer number 15 = Buffer memory addresses 1353 to 1356, 1471
Example:
⋅
A pointer number is assigned to each group of buffer memory
addresses that stores one complete error history record.
A pointer number 0 to 15 is assigned to each history record and
the record is stored in chronological order. A pointer number 0 is
reassigned to the 16th history record and the 16th record overwrites
the oldest history record.
