It shows that positioning is not yet completed. Check the contents of the
following diagnostic number. (It is 1 in the following condition)
DGN 0300
Position Error
>PARAM 1826
In–position width
1) Check the parameters according to the parameter list.
1825 Servo loop gain per axis (Normal : 3000)
2) Servo system may be abnormal. Refer to servo alarm 400, 410, and
411.
There are a plural interlock signals. Check at first which interlock signal
is used by the machine tool builder at the parameters shown below.

Check state of effective interlock signals using the diagnostic function
(PMCDGN) of the PMC.
1) Interlock signal (*IT) is input.
