Coordinates management
z Setting example of motorized actuator
The following is an example to set the home of a motorized actuator at the position of 30 mm from the motor side.
• Motorized actuator stroke: 600 mm
• Motorized actuator pitch: 6 mm/rev
Concept of initial coordinate
Initial coordinate generation range =
Wrap range o set ratio =
From the above, the actual coordinate is in the range of −5 to 95 revolutions.

„ Wrap function
The wrap function is a function to automatically preset the position information of the present position when the
number of revolutions of the motor output shaft exceeds the set range. Setting the wrap offset can restrict the
operation area of equipment or control an index table with coordinates on the positive and negative sides. Refer to
p.139 for the specific setting methods.
The wrap function is enabled at the time of shipment. Disable the wrap function when it is not used.
Set the parameters as follows.
Initial coordinate generation & wrap coordinate setting (47F2h): 1 (Manual setting)
Wrap (RND) setting (41C7h): 0 (Disable)
z Concept of wrap setting
With the wrap setting, 1,800 revolutions managed by the ABZO sensor are divided evenly to generate coordinates
within the number of revolutions divided evenly.
Therefore, set a value that becomes an integer when 1,800 is divided.
Example:
If the wrap function is activated when the motor rotates by 180 revolutions in the same direction.
Motor output shaft
0 to 180 revolutions
The present position of the motor is preset every 180 revolutions, however, the 32-bit counter in the driver is not
preset.
