MACHINE PARAMETERS
Px09
Indicates whether the axis position can be displayed in Radius and Diameters.
By default, the DRO shows the position value in radius which is the same as the
one given by the feedback device. The diameter display will show (if set to be
allowed) a position value twice that of the radius.
The diameter display is not possible on rotary axes.
Px10
Indicates the multiplying factor x2 or x4 that the DRO will apply to the feedback
pulses from this axis.
Px11
Indicates the multiplying factor x5, x10, x20 or x25 that the DRO will apply,
besides the one indicated in Px10, to the sinewave feedback signals from this axis.
Px12
Indicates the feedback (counting) resolution on this axis.
The maximum resolution is 0.0001mm/pulse or 0.000005 inch/pulse.
Example 1:
To obtain a 5µm resolution on a linear axis with square feedback signal.
The multiplying factor that the DRO applies to the square signals can be x2
or x4. Therefore, the scale used must have a grading pitch of 10µm or 20µm.
Grading pitch 20µm Grading pitch 10µm
Px05 = SQUARE Px05 = SQUARE
Px06 = LINEAR Px06 = LINEAR
Px07 = MM/DEG Px07 = MM/DEG
Px10 = x4 Px10 = x2
Px11 = — Px11 = —
Px12 = 0.005 Px12 = 0.005
