•
In the case of a virtual master axis, command values are cyclically
preset by the master via the master communication.
See also "Measuring Encoder" in chapter "Extended Drive Functions"
Note:
The master axis position can only be processed in a binary
format (1 master axis revolution = 2
be taken into consideration when using a real master axis
encoder and the encoder has to be selected accordingly.
Note:
The minimum/maximum value of P-0-0054, Additive master
axis position at maximum corresponds to the master axis
cycle (P-0-0750 * 2
Exception:
When P-0-0750, Master axis revolutions per master axis
cycle equals zero, the resulting maximum value for parameter
P-0-0054 is (231 – 1) increments and the minimum value is
–231 increments.

Function block "master axis evaluation" for real/virtual master axis
The command value input in the synchronization modes with real or
virtual master axis is carried out depending on the kind of master axis:
• real master axis:
A measuring encoder is cyclically evaluated in the position loop clock,
the master axis position is displayed in parameter P-0-0052, Actual
position value of measuring encoder.
• virtual master axis:
A virtual master axis position is cyclically preset in the NC clock via
parameter P-0-0053, Master axis position. This master axis position
is preset by the master in equidistant intervals.
