(1) Even if it has stopped, when the start accept flag (M2001 to M2032) is ON state,
the state where the request of speed change "0" is accepted is indicated.
Confirm by this speed change "0" accepting 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 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 servomotor axis.
