Functions deleted from those of A1SD75P1-S3/A1SD75P2-S3/A1SD75P3-S3

Deleted functions	Remarks
Stepping motor mode	–
OPR operation error (Error code: 208)	–
Fast machine OPR	–
Special start (stop)	–
	In the QD75, the start block area on the buffer memory is
Indirect designation	expanded to five blocks (0 to 4). Each start block can be directly
	designated with positioning start No. (7000 to 7004).
Block transfer	With the A1SD75, this interface is used to set positioning data
	Nos. 101 to 600 that do not exist on the buffer memory.
Positioning data I/F	Since all positioning data can be set in the buffer memory with the
	QD75, this function is deleted.
Start history storage during error	The contents are the same as those of the start history. Therefore,
	the QD75 stores only the start history.
	These data were deleted because they can be displayed in system
System monitor data (module type, OS information)	monitor "Module's detailed information" of GX Developer.
	(Refer to GX Developer Operating Manual.)

Functions changed from those of A1SD75P1-S3/A1SD75P2-S3/A1SD75P3-S3

Changed functions						Descriptions
	1.	The limit check of arc address is carried out only when a sub
		point is designated. It is not carried out when a center point is
		designated.
	2.	The software stroke limit check during speed control is carried
		out in the following cases:
		• When the software stroke limit is applied to the current feed
		value with				and the current feed value is updated with
					Pr.14
				.
			Pr.21
		• When the software stroke limit is applied to the machine feed
Software stroke limit function		value.
	3.	If an attempt is made to change the current value but the
		designated address is out of the software stroke limit range, the
		attempt is considered as an error and the current value is not
		changed.
	4.	The conventional models feature three types of software stroke
		limit error codes for upper limit and lower limit respectively. With
		the QD75, errors for the software stroke upper limit are
		integrated into error code 507, and errors for the lower limit are
		integrated into error code 508. Error codes 509 to 512 are
		deleted.
	1.	An error occurs when the designated new current value is out of
Current value changing		the software stroke limit range.
M code function	2. The M code setting value is valid during the positioning data
		current value changing instruction.
	1.	An error occurs when the command frequency value calculated
		from the speed limit value is out of the maximum command
Acceleration/deceleration control		frequency of the positioning module being used.
	2.	Only two-word type (1 to 8388608ms) can be used as the
		setting value for the acceleration/deceleration time. (The switch
		between 1-word type and 2-word type is eliminated.)
