5-1 Overview of coordinates management
The AZ Series manages the position coordinates of the motor with the ABZO sensor (mechanical multi-rotation
absolute sensor). The present coordinates are mechanically recorded inside the ABZO sensor. Therefore, even if the
motor output shaft is rotated by an external force when the control power supply is in an OFF state, the absolute
coordinates with respect to the home can be maintained.
Set the coordinates according to the following flow.
Connect a motor and a driver, and turn on the control power supply.
Initial coordinates are automatically generated.

Set the mechanical home.
Factory home or user home

Set the initial coordinates generation range and the wrap range.

Turn off the control power supply and on again.
Changed parameters will be enabled.

About ABZO sensor
The ABZO sensor is a mechanical multi-rotation absolute sensor that does not require a battery.
It stores the present position as an absolute position until the number of revolutions of the motor output shaft
exceeds 1,800 (*). The present position is stored even if the control power supply is turned off.
When the number of counts exceeds 1,800 revolutions (*), it is reset to 0 and is newly started from 1.
* The amount of multiple rotations varies depending on the motor frame size. Check on the following table.
Multiple rotation amount of ABZO sensor
Motor frame size [mm (in.)] Specifications of ABZO sensor
20 (0.79), 28 (1.10) 900 revolutions
40 (1.57), 42 (1.65), 60 (2.36),
85 (3.35), 90 (3.54)

Initial coordinate generation
“Initial coordinate generation” refers to determining how to use the rotation range of up to 1,800 revolutions (or 900
revolutions) that the ABZO sensor can manage. There are four parameters required for initial coordinate generation as
shown below. These parameters are read when the control power supply is turned on.
• Initial coordinate generation & wrap coordinate setting (47F2h)
• Initial coordinate generation & wrap setting range (41C9h)
• Initial coordinate generation & wrap range offset ratio (41CBh)
• Initial coordinate generation & wrap range offset value (41CCh)
Regardless of whether the wrap function is enabled or disabled, the initial coordinate is generated
when the control power supply is turned on.
