APPENDIX
(d) Absolute position detection system
When the travel distance from the home position exceeds the value calculated from 32767
(number
of encoder pulses per revolution) due to a unidirectional feed, etc., the absolute position cannot be
restored. To restore the absolute position, when turning off the power supply at a position out of the
range where the absolute position is restorable, establish the home position again by the home position
reset function or the home position return, and store the home position information (home position
multiple revolution data and home position within 1 revolution position) to the user program side.
