8.8.5. Teaching of Home Position Offset
 In the Home Return operation, you may set the home position to the point at where the Motor rotated a
given amount of rotation from the changed position of the detecting state of home limit sensor (from the
phase Z signal in some Home Return mode). The parameter HO (Home offset) sets this given amount of
rotation (offset).
 Home position offset function is available for the Home Return modes (Parameter OS) besides
the parameter OS6.
 Teaching of home position offset is only effective right after an execution of the command
HS/LS.
 This section describes a way to set the parameter HO by teaching.
1) Execute the command HS/LS and finalize the position of home limit sensor.
 Refer to “8.8.4. Position Adjustment of Home Limit Sensor.”
2) Turn off the main power supply to the Driver Unit.
3) Input the command MO (Motor off)

Thus the Motor servo will not activate even the input SVON is activated.
4) Move the motor to a position to be the home position.
5) Teach the direction and amount of rotation to the current position as the offset.
(The parameter HO requires an entry of the password.)
