• During machine program operation, "[St.1048] Automatic decelerating flag (R: M30208+n/Q: M2128+n)" turns ON while
automatic deceleration is performed during the execution of positioning at the final point.
• The signal turns off when all normal start complete commands became achieve.
• The "[St.1048] Automatic decelerating flag (R: M30208+n/Q: M2128+n)" might be turned ON even during acceleration at
advanced S-curve acceleration/deceleration. (Page 221 Advanced S-curve acceleration/deceleration)
• In any of the following cases, "[St.1048] Automatic decelerating flag (R: M30208+n/Q: M2128+n)" does not turn on.
• During deceleration due to JOG signal OFF
• During deceleration due to machine JOG signal OFF
• During manual pulse generator operation
• During deceleration due to stop command or stop cause occurrence
• When travel value is 0
• During machine program operation due to sequential coordinate command control

(R: M30208+n/Q: M2128+n)
[St.1049] Speed change "0" accepting flag (R: M30272+n/Q: M2240+n)
This flag turns on while a speed change request to speed "0" or negative speed change request is being accepted.
It turns on when the speed change request to speed "0" or negative speed change request is accepted during a start. After
that, this signal turns off when a speed change is accepted or on completion of a stop due to a stop cause.
This flag also turns on when the override ratio for the override function is set to "0". After that, this signal turns off when the
override ratio is set to a value other than "0" or on completion of a stop due to a stop cause.

• Even if it has stopped, when the "[St.1040] Start accept flag (R: M30080+n/Q: M2001+n)" is ON state, the
state where the request of speed change "0" is accepted is indicated. Confirm by this "[St.1049] Speed
change "0" accepting flag (R: M30272+n/Q: M2240+n)".
• During interpolation, the flags corresponding to the interpolation axes are set.
• In any of the following cases, the speed change "0" request is invalid.
(1) After deceleration by the JOG signal off
(2) During manual pulse generator operation
(3) After positioning automatic deceleration start
(4) After deceleration due to stop cause
