• Confirm the teaching function and teaching procedure before setting the positioning data.
• The positioning addresses that are written are absolute address (ABS) values.
• The positioning data written by the teaching function overwrites the data of buffer memory only. Therefore,
read from buffer memory and write to flash ROM before turning the power OFF as necessary.
