4.2 Operations with the axes
4.2.1 Home search
It is the operation used to synchronize the system. This operation must be carried
out when the CNC loses the position of the origin point (e.g. by turning the machine
off).
When "searching home", the axes move to the machine reference point and the CNC
assumes the coordinate values assigned to that point by the machine manufacturer,
referred to machine zero. When using distance-coded reference marks or absolute
feedback, the axes will only move the distance necessary to verify their position.
The axes may be homed manually or automatically.
• Manual homing is done one axis at a time, from the operator panel.
• Automatic homing is done with a subroutine defined by the machine
manufacturer.
Manual home search
It is done one axis at a time. Home search of an axis is carried out as follows:
Automatic home search
This homing method is only available if the machine manufacturer has previously
defined a homing subroutine.
Home search using a subroutine is carried out as follows:
1. Select the axis to be homed using the alphanumeric keyboard. The CNC will
highlight that axis to indicate that it is selected.
To select the numbered axes (e.g. "X1"), select any axis and then move the
selection until positioning on the desired one. The focus moves with the [

keys.
2. Press the homing key [ZERO]. The CNC will display the "1" symbol in the numeric
area indicating that a home search will take place.
3. Press [START] to go ahead with the home search or [ESC] to cancel the operation.
When searching home in this mode, the CNC cancels the zero offset, the
fixture offset and the measuring offset. It assumes the machine reference zero
point (home) as the new part zero.
i
1. Press the homing key [ZERO]. The CNC will display a dialog box requesting
confirmation to execute the home search.
2. Press [START] to go ahead with the home search or [ESC] to cancel the operation.
