6.2 SETTING THE REFERENCE POSITION WITHOUT DOGS
This function moves the machine to around the reference position set
for each axis in the manual continuous feed mode. Then it sets the
reference position for the machine in the manual reference position
return mode without the deceleration signal for reference position
return. With this function, the machine reference position can be set at
a given position without the deceleration signal for reference position
return.
- Setting the reference position
1 Place the machine in the manual continuous feed mode, and
perform positioning to a position near but not exceeding the
reference position from reference position return direction
(setting by parameter).
2 Enter the manual reference position return mode, then input the
feed axis direction select signal (+) or (-) for the axis.
3 Positioning is made at the grid point located nearest from the
current point to reference position return direction. This point is
recorded as the reference position. If the absolute-position
detector is provided, the set reference position is retained after the
power is turned off. In this case, when the power is turned on
again, there is no need for setting the reference position again.
- Reference position return
1 After the reference position is set, when the feed axis select signal
(+) or (-) is input for the axis in the reference position return mode,
reference position return operation is performed in rapid traverse
regardless of which signal (+) or (-) is input.
