MACHINE PARAMETERS.
(REF: 1402)
Machine parameters for the axes. Work sets.
In order for the CNC to show the position with respect to Machine Zero (M), this parameter
must be assigned the position of the machine zero (M) with respect to the glass zero point (C).
The zero point of the glass (beginning of the distance code) may be in or out the scale's
measuring length.
EXTMULT
External factor for distance-coded reference marks.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drives and simulated drives.
Possible values: From 0 to 65535.
Default value: 0.
Associated variable: (V.)[ch].MPA.EXTMULT[set].xn
The CNC takes this parameter into account if I0TYPE = Distance coded.
This parameter indicates the relationship between the mechanical period (of the graduation
on the glass) and the electrical period (of the feedback signal) being applied to the CNC.
Values to be assigned for Fagor encoders with distance-coded I0.
I0CODDI1
Pitch between 2 fixed distance-coded reference marks.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 65535.
Default value: 1000.
Associated variable: (V.)[ch].MPA.I0CODDI1[set].xn
See machine parameter I0CODDI2.
(C) Zero position of the glass.
(M) Machine reference zero position.
Example with a Fagor linear encoder.
A "FOX" type Fagor linear encoder has a graduation period of 100 µm (gap between lines)
and an electrical signal period of 4 µm.
