3 POSITIONING DEDICATED SIGNALS
(15) Automatic decelerating flag (M2128 to M2159) ........ Status signal
This signal turns on while automatic deceleration processing is performed
during the positioning control or position follow-up control.
(a) This flag turns on while automatic deceleration to the command address at
the position follow-up control, but it turns off if the command address is
changed.
(b) This signal turns on while automatic deceleration processing is performed
during execution of positioning to final point while in constant speed control.

POINT
Set a travel value in which automatic deceleration processing can be started at the
final positioning point, therefore the automatic decelerating flag turns on at the start
point of automatic deceleration processing after this final point.
(c) The signal turns off when all normal start complete commands became
achieve.
(d) The automatic decelerating flag (M2128+n) might be turned ON even
