Ramp-down stop
 When M10 is ON, the DDRVI instruction is executed and starts to output pulses, and SM460, the Busy flag
is ON.
 When the instruction is disabled (M10 is OFF) or the stop flag SM463 is ON, the state of the immediately
stop flag SM476 is confirmed.
 If the immediately stop flag SM476 is OFF, the output ramps down to stop and then the Busy flag SM460
is OFF.
 If M10 is not OFF and the stop flag SM463 is not ON after the instruction is executed, Y0.0 stops the output
after 20,000 pulses.
c)
Immediately stop
 When M10 is ON, the DDRVI instruction is executed and starts to output pulses, and SM460, the Busy flag
is ON.
 If the instruction is disabled (M10 is OFF) or the stop flag SM463 is ON, the state of the immediately stop
flag SM476 is confirmed.
 If the immediately stop flag SM476 is ON, the output stops immediately and the Busy flag SM460 is OFF.
