POSITIONING MODULE REPLACEMENT

7.4.2 Function comparison

(1) Deleted function from AD75P1-S3/P2-S3/P3-S3
When using the following function on AD75P-S3, change the program.
Deleted functions
Stepping motor mode
Fast machine OPR
Special start (stop)
Indirect designation
Block transfer
Positioning data I/F
Start history during errors
System monitor data
(Module name, OS type, OS version)
The setting is not required when using stepping motor due to it's performance gain.
With the QD75PN/QD75DN, there is no possible function for replacement.
Execute it separately for the start two times.
In the QD75PN/QD75DN, the start block area on the buffer memory is expanded to five blocks (0
to 4).
Each start block can be directly designated with positioning start No. (7000 to 7004).
With the AD75P-S3, this interface is used to set positioning data Nos. 101 to 600 that do not exist
on the buffer memory.
Since all positioning data can be set in the buffer memory with the QD75PN/QD75DN, this
function is deleted.
The contents are the same as the start history.
Therefore, the QD75PN/QD75DN stores only the start history.
These data were deleted because they can be displayed in system monitor "Module's detailed
information" of GX Developer.
(Refer to GX Developer Operating Manual.)
