Mitsubishi Electronics QD75D Changed functions, Normal Not Ready Ready signal, Not Ready Normal

APPENDICES			MELSEC-Q
Changed functions		Descriptions
	1. "Peripheral side (emergency) stop" is deleted from the stop
	causes of Stop group 2 sudden stop selection. "Test mode fault"
	in the stop causes of Stop group 3 sudden stop selection is
	changed to be in the stop causes of Stop group 2 sudden stop
Stop process and restart after stop	selection.
	2. "Stop (QD75 peripheral)" is added to the stop causes of Stop
Positioning operation stop
	group 3 sudden stop selection.
	3. Error code 100 (Peripheral device stop during operation) is
	deleted.
	4. "PLC CPU error occurrence" is added to the stop causes of
	Stop group 2 sudden stop selection.
		A1SD75	QD75
	OFF	Normal	Not READY
READY signal (X0)		(READY)	/WDT error
	ON	Not READY	Normal
		/WDT error	(READY)
Manual pulse generator operation	The No. of connectable manual pulse generator is changed from 1
	generator/1 axis to 1 generator/1 module.
	"Step stopped" is changed to "Stopped" and "Step error occurring"
	is changed to "Error occurring".
Axis operation status	"In position control for position-speed switching control", "In speed
	control for position-speed switching control", and "In absolute
	position restoration" are added.
	A1SD75: If the reference axis operates in reverse direction, the
	control is internally changed into the continuous
	positioning control (restart after deceleration stop).
Continuous path control	QD75: Even if the reference axis operates in reverse direction with
	interpolation, the control remains as the continuous path
	control. (In single-axis operation, the operation is the same
	as that of the A1SD75.)
Near pass	For the continuous path control, only the near pass function is
	available.
2-axis interpolation
• 2-axis linear interpolation	The interpolation target axis can be randomly set with a positioning
• 2-axis fixed-feed
	identifier.
• Circular interpolation
• 2-axis speed control
	1. "Step stopped" is changed to "Stopped" and "Step error
	occurring" is changed to "Error occurring" in the axis operation
Step function	status parameters.
	2. The restart command for step start information (02H) is deleted.
	3. The step operation is restarted with the restart command.
	The command in-position width is expanded.
Command in-position function	• A1SD75: 1 to 32767000
	• QD75: 1 to 2147483647
Control unit "degree" handling	The operating direction can be designated even for the ABS
	control in the unit of "degree".
