Definition
Origin search mode is the way of heading to origin with command of Control word (6040h). To use origin search
mode, need to set Homing Mode at Mode of operation (6060h). Able to use origin search command once Mode
of operation display (6061h) indicates Homing Mode.

There are 4 kinds (Origin Switch, Positive Limit Switch, Negative Limit Switch, Index pulse of Encoder) switches to
find out origin. And it can be
differentiated
by Homing Method (6098h). If it is not Homing method by Limit Switch,
once Limit Switch goes ON during origin searching, it will move to opposite direction against movement direction.
During motion towards opposite direction, if opposite side of Limit Switch goes ON, origin search goes failure. If
Sensor origin and mechanical origin is
different,
able to set with using Home
Offset
(607Ch). Once position of
mechanical origin is set to Home
Offset,
Status word
- bit 12: Home Attained is going to be ON and position objects will be initialized.
