Wrap range offset value setting
The coordinates can be shifted in a step unit for the coordinate system having offset with the Initial coordinate
generation & wrap range offset ratio (41CBh).
When the coordinates are set with the Initial coordinate generation & wrap range offset value
(41CCh), information of Wrap setting error is generated if the home is not included in the coordinates.
If the main power supply and the control power supply are turned on again or Configuration is
executed in a state where information of the Wrap setting error is generated, an alarm of the Wrap
setting error will be generated.
Setting example 1: When the wrap range is 1,800 rev, the resolution is 10,000 P/R, and the wrap offset
ratio setting is 50 %.
Wrap range offset value = 0 step
Wrap range offset value = 1,000 step

RND-ZERO output
The RND-ZERO output is a signal that is output for each division boundary point when the wrap range is divided
evenly with the home as a reference.
The number of divisions can be set with the The number of the RND-ZERO output in wrap range (41CDh). The RND-
ZERO output is output when the Wrap setting (41C7h) is set to "1: Enable."
z
Example of use 1
When the RND-ZERO signal is output for every rotation of the output shaft
(In case of wrap range of 1,800 rev and a geared motor of gear ratio 7.2)

This example of use can check that the position of the motor is in the home. With a geared motor, it can be used as a
phase Z signal that outputs one pulse for every rotation.

This example of use can output a signal regularly during operation of the motorized actuator or hollow rotary
actuator. It can be used to synchronize multiple motors and to operate by inputting the RND-ZERO signal to other
system.
