Section 8-3
8-3
Present Position Preset
PRESENT POSITION PRESET changes the present position to any position
and then establishes the origin.
8-3-1
Outline of Operation
When the PRESENT POSITION PRESET Bit is turned ON, the present posi-
tion is changed to the value set as the position command value in the Axis
Operating Output Memory Areas. during present position preset, the Busy
Flag is ON (1 cycle time min.). The Busy Flag turns OFF to indicate that pre-
set operation has been completed. After this, the origin is established. If the
present position is changed to “0,” then that position will become the origin.
