Setup
Machine reference point (home) adjustment for each axis
Once the movement of the axes has been properly adjusted, place the travel-limit switches back
where they should be.
The following adjusting sequence is one of the many that could be used:
• This adjustment should be done one axis at a time.
• Indicate in the axis parameter REFPULSE (P32) the type of marker pulse Io being used for Home
Search.
• Set axis parameter REFDIREC (P33) to indicate the direction of the axis when searching Home.
• Set axis parameters REFEED1 (P34) and REFEED2 (P35) to indicate the feedrates for Home
search.
• axis parameter REFVALUE (P36) will be set to "0".
• Once in the JOG mode and after positioning the axis in the right area, start homing the axis.
When done, the CNC will assign a "0" value to this point.
• If the machine reference zero is in a different physical location from the machine reference point
(location of the marker pulse), proceed as follows:
After moving the axis to a known position (with respect to Machine Reference Zero), observe
the position reading of the CNC for that point.
This will be the distance away from the machine reference point; thus, the value to be assigned
to axis parameter REFVALUE (P36) will be:
Machine coordinate of the measured point - CNC reading at that point.
Example:
If the point whose known position is located 230 mm from Machine Reference Zero and the CNC
reads -123.5 mm as the coordinate value for this point, the coordinate of the Machine Reference
Point with respect to Machine Reference Zero will be:
REFVALUE = 230 - (-123.5) = 353.5 mm.
Assign this new value and press [RESET] so it is assumed by the CNC.
It is also necessary to search Home once again in order for this axis to assume the correct
reference values.
Axis travel limits (software limits)
Once all the axes have been referenced, their software limits must be measured and set.
This is achieved a single axis at a time as follows:
• Move the axis in the positive direction towards the end of the axis travel stopping at a safe
distance from the mechanical end-of-travel stop.
• Assign the coordinate shown by the CNC for that point to axis parameter LIMIT+ (P5).
• Repeat these steps in the negative direction assigning the resulting coordinate to axis parameter
LIMIT- (P6).
• Once this process is completed, hit SHIFT RESET or turn the CNC off and back on in order for
it to assume the new values.
