Machine parameters for the axes. Work sets.
REFFEED1
Fast home searching feedrate.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 200000.0000 mm/min or degrees/min / from 0 to 7873.992 inch/min / from
0 to 100000.0000 rpm.
Default value: 1000.0000 mm/min or degrees/min / 39.37001 inch/min / 100.0000 rpm.
Associated variable: (V.)[ch].MPA.REFFEED1[set].xn
See machine parameter REFFEED2.
REFFEED2
Slow home searching feedrate.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 200000.0000 mm/min or degrees/min / from 0 to 7873.992 inch/min / from
0 to 100000.0000 rpm.
Default value: 100.0000 mm/min or degrees/min / 3.93700 inch/min / 10.0000 rpm.
Associated variable: (V.)[ch].MPA.REFFEED2[set].xn
When the feedback system does not have distance-coded reference marks (I0, the home
search is carried out at the feedrate indicated by "REFFEED1" until the home switch is
reached. It then reverses its movement at the feedrate indicated by "REFFEED2" and it goes
on until the CNC receives the reference marker pulse from the feedback device.
REFPULSE
Type of I0 pulse.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: Positive / Negative.
Default value: Positive.
Associated variable: (V.)[ch].MPA.REFPULSE[set].xn
This parameter indicates the type of flank of the I0 signal that is used for home search.
POSINREF
Home search moving the axis to the reference point.
Parameter valid for linear and rotary axes.
Parameter valid for analog drive, Sercos and simulated.
Possible values: Yes / No.
Default value: No.
Associated variable: (V.)[ch].MPA.POSINREF[set].xn
This parameter indicates whether the axis moves or not to the machine reference point
(parameter REFVALUE) while homing. This movement is not necessary when the axis has
internal absolute feedback (motor feedback).
On axes with absolute motor feedback, the CNC knows at all times the relative axis position
per motor revolution. In these cases, while homing the axis, the CNC knows its position as
soon as the home switch is pressed; hence not being necessary to move up to the reference
point.
ABSOFF
Offset with respect to the distance-coded ref. mark.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: Within ±99999.9999 mm or degrees / within ±3937.00787 inch.
Default value: 0.
Associated variable: (V.)[ch].MPA.ABSOFF[set].xn
The CNC takes this parameter into account if I0TYPE = Distance coded or ABSFEEDBACK
= Yes.
With linear encoders with distance-coded (I0 reference marks, it is possible to know the
position of the machine by simply moving the axis a distance of 20 or 100 mm. After reading
two consecutive distance-coded reference marks (20 or 100 mm away from each other), it
is possible to know the axis position with respect to the zero point of the graduated glass (C).
