Setting the output width of signals related to the set position
Set the following signals: Set position reached (JST) which indicates the machine has completed positioning, detection width
of Automatic set position reached (JSTA), and detection width of Near set position (NEAR) which indicates that the machine is
near to any stations.

Explanations
Set position reached (JST) indicates that the machine posi-
tion stays at any one of the stations. During automatic opera-
tion, Automatic set position reached (JSTA) is detected under
the same conditions.
Set the tolerable values at which these signals are output
when each operation parameter group is selected. These sig-
nals turn OFF when the machine position is away from the
station by more than this value.
The signal indicating that the machine position stays near to
one of the stations is the near set position (NEAR) signal. Set
the tolerable values at which this signal is output when each
operation parameter group is selected. Generally set the tol-
erable value larger than set position output width.
Operations are related to special commands when Station se-
lection is set to "0".
