To perform a critical adjustment, proceed as follows:
• Verify that there are no oscillations of following error, In other words, that it is not unstable.
• Check,with an oscilloscope, the tacho voltage or the command voltage at the drive (velocity
command), verify that it is stable (left graph) and that there are no instabilities when starting up
(center graph) or when braking (right graph).
Machine reference point setting
To set the machine reference point proceed as follows:
• Indicate in the s.m.p. REFPULSE (P32) the type of marker pulse Io being used for Home Search.
• Likewise, set s.m.p. REFDIREC (P33) to indicate the direction of the axis when searching Home.
• On the other hand, set s.m.p. REFEED1 (P34) that defines the approach feedrate of the spindle
until the home switch is pressed and s.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". s.m.p. REFVALUE (P36).
• Once in JOG mode and after positioning the spindle in the right area, start homing the spindle.
When done, the CNC will assign a "0" value to this point.
• After moving the spindle 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.
This will be distance from the Machine Reference Zero to that point. Therefore, the value to be
assigned to s.m.p. REFVALUE (P36), which defines the coordinate corresponding to the
Machine Reference Point (physical location of the marker pulse).
REFVALUE (P36) = Machine coordinate – CNC reading.
