4.7 File Transfer Function
File transfer operation
• Operation when the file transfer target is a servo parameter file is as follows.
• Operation when the file transfer target is a cam file is as follows.
When the execution command (FFFEH) is accepted, "Cam data writing (SM505)" turns ON, and then turns
OFF when file transfer is complete. The system will be executing a CAMRD, CAMWR, or CAMM command
when the execution command is accepted, and therefore if "Operating cam data (SM505)" is ON, file transfer
will not be executed, and the "File transfer status (SD554)" will change to error completion (-100).
Request Target axis Operation
Built-in
memory to file
transfer
Any given 1 axis • The target axis servo parameter open area content is written to the servo parameter file.
• If an error occurs during execution, the servo parameter file is not updated.
All axes • The servo parameter open area content is written to the servo parameter file in order of the smallest system setting
axis No. first.
• When transfer is complete for all axes, the "File transfer status (SD554)" changes to "0: Awaiting request
acceptance".
• If an error occurs with any of the files, transfer is terminated for the axis at which the error occurred and after.
File to built-in
memory
Any given 1 axis • The target axis servo parameter file content is read to the servo parameter open area.
• If an error occurs during execution, the servo parameter open area is not updated.
All axes • The servo parameter file content is read to the servo parameter open area in order of the smallest axis No. set in the
system.
• When transfer is complete for all axes, the "File transfer status (SD554)" changes to "0: Awaiting request
acceptance".
• If an error occurs with any of the files, transfer is terminated for the axis at which the error occurred and after.
Request Target cam No. Operation
File to built-in
memory
Any given 1 file • The target cam file content is read to the cam open area.
• If an error occurs during execution, the cam open area is not updated.
All cam files • The content of the cam file in the folder is read to the cam open area one item at a time.
• When transfer is complete for all axes, the "File transfer status (SD554)" changes to "0: Awaiting request
acceptance".
• If an error occurs for any files, expansion of that file is terminated, and the next cam file is transferred. (The "File
transfer status (SD554)" changes to "-100: Error completion".)
