7.2. For More Advanced Operation
7.2.1. Absolute Position Scale (For Absolute Position Sensor)
7.2.1.3. Offsetting Position Data
l This System provides the position scale (user absolute position scale) along which every
positioning operation and setting of over travel limit shall be controlled. The user absolute
position scale is defined by offsetting position on the position scale that is unique to each Motor
(Motor absolute position scale) by use of the built in "one revolution absolute position sensor."
l The AO data (AO command) sets the offset value.
l The AO data will be automatically set when the home position is defined by the AZ command.
l Relations between the Motor absolute position scale, the user absolute position scale and the AO
data shall be;
[Example] AO data = 10 000 [pulse]
