13.4 Home Change

The current value update is a function to change the current value managed in the positioning unit to an
arbitrary value.
Data must be written into the shared memory from the PLC in order to carry out the current value update.
Followings are the details of the shared memory to carry out the current value update.

Procedures of current value update
1. Write an coordinate to be the current value in the current value update coordinate area of the target
axis.
2. Write the value at the time that the bit of the target axis set to 1 in the current value request flag area.
As the current value update process is performed for the axis that is 1 in the current value request flag
area, do not set any bit to 1 other than the target axis.
3. The current value after unit conversion in each axis information and monitor area is changed to the
specified current value.
Note: The value to be changed by updating the current value is the current value after unit
conversion.
Descriptions
Only when the corresponding bits for each axis changed to 1 from 0, the current
valuecooridnate managed in the positioning unit is changed to the following
current value update coordiate.
Afther the change, the positioning unit clears the corresponding bits to 0
automatically.
