POSITIONING MODULE REPLACEMENT

7.2.2 Functional comparison

(1) Functions deleted from the A1SD75P-S3
When the following functions are used with the A1SD75P-S3, change the program.
When the built-in I/O functions of the LCPU are used, refer to the MELSEC-L CPU Module User's
Manual (Built-in I/O Function).
Deleted function
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)
Requires no setting of when the stepping motor is used to improve its performance.
With the LD75P/D, there is no possible function for replacement.
Execute it separately for the start two times.
In the LD75P/D, the start block area in the buffer memory is expanded to five blocks (0 to
4).
Each start block can be directly specified with Positioning start No. 7000 to 7004.
With the A1SD75P-S3, this interface is used to set Positioning data No. 101 to 600 that do
not exist in the buffer memory.
Since all positioning data can be set in the buffer memory with the LD75P/D, this function is
deleted.
The contents are the same as the start history. Therefore, the LD75P/D stores only the
start history.
These data were deleted because they can be displayed in system monitor "Module's detailed
information" of GX Works2.
(For details, refer to the GX Works2 Operating Manual.)
