Note
The positions are saved on the SD card only through FCT. And so
when jog/teach (without FCT) is used, an SD card may not be
plugged in or “Read from SD after restart” must be inactive;
otherwise, when the controller is restarted, the old values will be
read off the SD card again.
Activating jog/teach function
The jog/teach function is started in I/O operation through selection of mode 1.
