The speed change "0" accepting flag is ON while a speed change request for
speed "0" is being accepted.
This signal turns ON when the speed change request for speed "0" is
accepted during a start. After that, this signal turns OFF when a speed change
to other than speed "0" is accepted or on completion of a stop due to a stop
cause.

REMARK
(1) Even during a stop, the ON status of the start acceptance flag (M2001 to
M2032) indicates that the speed change "0" request is accepted. Check
with this speed change "0" flag.
(2) During interpolation, the flags corresponding to the interpolation axes are
set.
(3) In any of the following cases, the speed change "0" request is invalid.
• After deceleration due to JOG OFF
• During manual pulse generator operation
• After positioning automatic deceleration start
• After deceleration due to stop cause
(4) In the SV22 virtual mode, the flag is that of the virtual servo motor shaft.
