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.
