3 POSITIONING DEDICATED SIGNALS
(16) Speed change "0" accepting flag (M2240 to M2271)
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.

REMARK
(1) Even if it has stopped, when the start accept flag (M2001+n) is ON state, the
state where the request of speed change "0" is accepted is indicated.
Confirm by this speed change "0" accepting flag (M2240+n).
(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 by the JOG signal off
• During manual pulse generator operation
• After positioning automatic deceleration start
• After deceleration due to stop cause
(4) During the SV22 virtual mode, the flag is that of the virtual servo motor axis.
