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)
