For both master axes it is possible to change, via parameter
P-0-0054,
Additive master axis position
, the master axis position by an additive
component (= offset) in the NC cycle clock:
•
real master axis:
The resulting master axis position (P-0-0052 + P-0-0054) is not fine
interpolated, but limited in modulo form to the master axis range
(modulo value master axis = P-0-0750 * 2
20
) via
P-0-0750, Master
axis revolutions per master axis cycle
.
•
virtual master axis:
The resulting master axis position (P-0-0052 + P-0-0054) is linearly
fine interpolated in the position loop clock and limited in modulo form
to the master axis range (modulo value master axis = P-0-0750 * 2
20
)
via
P-0-0750, Master axis revolutions per master axis cycle
.
Note:
The master axis range is set as an integral multiple of a
master axis revolution (=
2
20
increments) with parameter
P-0-0750, Master axis revolutions per master axis cycle
.
Display of results of master axis processing:
•
The master axis speed is generated by differentiating the master axis
position in the NC clock and displayed in parameter
P-0-0764, Master
axis velocity
.
•
The modulo-limited (and fine interpolated, with virtual master axis)
master axis position is displayed in parameter
P-0-0775, Resulting
master axis position
.
Electronic Gear Function with Fine Adjust
The input value for the electronic gear is the resulting master axis position
(P-0-0775).

Function block "electronic gear with fine adjust"
The function block "electronic gear with fine adjust" is divided into the
following subfunctions:
•
electronic master axis gear with fine adjust
The master axis position or master axis velocity is first multiplied with
the factor from P-0-0157/P-0-0156 (output revolutions/inputs
revolutions).
By multiplying the resulting master axis position or master axis velocity
with the value 1 + P-0-0083 (gear ratio fine adjust) the fine adjust is
carried out.
