Positioning	Set "Positioning complete" assuming the next positioning data will not
	be executed. ("Continuous path control" cannot be set in "speed-
complete
	position switching control (ABS mode)".)
Forward run:	Set speed-position switching control by forward run.
speed/position
	Designate the value set in "		Acceleration time 1" as the
1		Pr.25
	acceleration time at start.
	Designate the value set in "		Deceleration time 0" as the
0		Pr.10
	deceleration time at deceleration.

–Setting not required. (Setting value is ignored.)

	ABS mode ( Pr.150 = 2)
270.00000	Set the address after the switching to position control. (Assuming that
degree
	the "		Unit setting" is set to "mm".)

–Setting not required. (Setting value is ignored.)

Da.8	Command speed	6000.00mm/min Set the speed to be controlled.
Da.9			Set a time from the positioning stop (pulse output stop) by position
	Dwell time	500ms	control until the positioning complete signal is output. When the
			system is stopped by speed control, ignore the setting value.
	M code	10	Set this when other sub operation commands are issued in
