Installation manual Setting on systems without distance-coded feedback Machine reference point The reference point must be adjusted on one axis at a time. The following procedure is recommended: • Indicate in the a.m.p. REFPULSE (P32) the type of marker pulse Io being used for Home Search. • On the other hand, set a.m.p. REFEED1 (P34) that defines the approach feedrate of the axis until the home switch is pressed and a.m.p. REFEED2 (P35) that indicates the homing feedrate until the reference mark (marker pulse) is detected. • The machine reference point will be set to "0". a.m.p. REFVALUE (P36). • 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. • After moving the axis to the Machine Reference Zero or up to a known position (with respect to Machine Reference Zero), observe the position reading of the CNC for that point. Reference systems 7. • Likewise, set a.m.p. REFDIREC (P33) to indicate the direction of the axis when searching Home. CONCEPTS 7.6.2 This will be distance from the Machine Reference Zero to that point. Therefore, the value to be assigned to a.m.p. REFVALUE (P36), which defines the coordinate corresponding to the Machine Reference Point (physical location of the marker pulse). REFVALUE = Machine coordinate – CNC reading. 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. • After assigning this new value, press [RESET] so it is assumed by the CNC. • The axis must be homed again in order for it to assume its right reference values.
