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.102 for the specific setting methods.
To set the wrap function, change the Initial coordinate generation & wrap coordinate setting (47F2h)
to "1: Manual setting." [Initial value: 0 (Prioritize ABZO setting)]
When this parameter is changed, turn off the main power supply and control power supply of the
driver, and on again.

Concept of wrap setting
This example explains using the motor of the frame size 60 mm (2.36 in.).
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, only a divisor (divisible value) of 1,800 can be set.
Example: If the wrap function is performed when the motor rotates 180 times in the same direction
Motor output shaft
0 to 180 revolutions
Wrap coordinate
0
180
360
540
1,800
Motor output shaft
Number of
revolutions (rev)
0
180
The present position of the motor is preset every 180 revolutions, however, the 32-bit counter in the driver is not
preset.
Example: When the range of use of the motor is offset to −90 to 90 revolutions
Motor output shaft
–90 to 90 revolutions
Wrap coordinate
0
180
360
540
1,800
Motor output shaft
Number of
revolutions (rev)
–90
0
90
When the wrap setting range is exceeded, the sign is reversed.
