PAR01 Feedback resolution. Independent for each axis.
Possible values: from 0.1µm up to 1 mm
Factory setting: 5 (µm).
PAR02 TTL multiplying factor (subdivision). Independent for each axis.
Options: x4, x2, x1 and x0.5.
The selection of these values rotates by pressing
The factory setting is: x4 and it is the one used for FAGOR scales.
When using encoders, it should be calculating according to the
number of pulses of the encoder, leadscrew pitch and the desired
resolution as per the formula:
Encoder (lines/turn) = Leadscrew pitch (mm/turn)
Where "xF" would be the multiplying factor to be applied.
PAR03 External multiplying factor for when using semi-absolute feedback
devices (distance-coded Io) or sinewave signals (NV-301T).
Independent for each axis.
Options: 1, 5, 10, 20, 25, 50.
Factory setting: 1
For example, for FAGOR scales: M0X, C0X or FOT, set this
parameter to 5.
PAR05 Scaling or shrink factor. Independent for each axis, numeric value
within ±9,999.
A "0" value means that no factor is to be applied. It is applied onto
the coordinates to be displayed after compensating for table sag. It
is not applied when reading with respect to machine reference cero
(
The factory setting is: "0".
