4.6.1. Parameter Setup of Backing to Machine Origin
The parameter REF. PointSet includes the setting of REFP Speed, REFP Dir and Retract Dist.
Press Menu→ 5. Mfr Param→ 5. REF. PointSet, and then press the [OK] key to enter the setting
interface of backing to machine origin, in which press the Up or Down key to select the corresponding
parameter to be modified.
REFP Speed: it is the speed of rough positioning during backing to machine origin, i.e. the motion
speed of an axis towards the home switch during rough positioning. The value of this parameter
should be set in accordance with the integral structure of a machine tool. And too fast speed can
cause missing steps, damage to the machine tool or to the home switch due to axis crash.
REFP Dir: it is the direction of rough positioning during backing to machine origin, i.e. the motion
direction of an axis towards the home switch during rough positioning. This parameter is decided by
the motor direction and installation position of the home switch; at the same time, it is also related
with the defined attribute of the input level and the attribute of the home switch.
Retract Dist: this parameter is decided by the machine tool itself. After arriving at the machine
origin, the machine tool will move some distance away from the machine origin to get out of the
signal sensitive zone of the home switch. Its value is recommended as half of the screw pitch.
4.6.2. Operation Mode of Backing to Machine Origin
After system start-up, pressing [OK] in the dialog box shown in Fig. 4-7 will home all the axes.

This method can only home all the axes. If you want to execute single axis backing to machine origin,
refer to the following steps.
Press the Menu key→ 3. Operations→ 1. Back REF Point, and then press the [OK] key to enter the
setup interface of backing to machine origin, in which press the Up or Down key to select the desired
mode. And then press the [OK] key to execute backing to machine origin in the selected way. It is
recommended to execute Z Home firstly. If X Home or Y Home is executed firstly, a message as
shown below will be displayed on the LCD prompting to execute Z Home firstly. To see all the
