Example:
If the point whose known position is located at 12º mm from Machine Reference Zero and
the CNC reads -123.5º as the coordinate value for this point, the coordinate of the Machine
Reference Point with respect to Machine Reference Zero will be:
"REFVALUE" P36 = 12 - (-123.5) = 135.5º
• After allocating this new value, press SHIFT + RESET or turn the CNC off and back on in order
for the CNC to assume this new value.
• The spindle must be homed again in order for it to assume its right reference values.
Considerations
If at the time when the home search is requested, the spindle is sitting on the home switch, the spindle
will back up (in the direction opposite to the one indicated by "REFDIREC (P33) ") until it is off the
switch and then, it will go on to search home.
Care must be taken when placing the home switch and when setting feedrates "REFEED1 (P34)"
and "REFEED2 (P35)". The home switch (1) will be installed so the marker pulse (2) will be found
in the zone corresponding to feedrate "REFEED2" (P35). If there is no room for it, reduce the value
of "REFEED1 (P34)". For example, for encoders whose consecutive marker pulses are very close
to each other.
When the spindle does not have a machine reference (home) switch (s.m.p. DECINPUT (P31) =
NO), the CNC will move the spindle at the feedrate set by s.m.p. REFEED2 (P35) until the first marker
pulse from the current position is found, thus ending the home search.
Fagor rotary encoders provide one positive reference pulse per revolution.
Do not mistake the type of pulse provided by the feedback system with the value to be assigned
to s.m.p. REFPULSE (P32).
This parameter must indicate the type of active flank (leading or trailing edge), positive or negative
of the reference mark (Io) used by the CNC.
