spindle
C
:
Datum shift in C axis
CM : Measuring pt. coordinate – Set current position to the
defined value
Setting the datum of the C axis:

Expanded form view for machines with counter spindle
If your machine is equipped with a counter spindle, the CA
parameter is shown. The CA parameter enables you to specify for
which workpiece spindle (main spindle or counter spindle) entries
for the
Set C-axis values function are effective.
The active angle offset is shown in the CV parameter. An angle
offset is activated with G905 to match the position of main
and counter spindle to each other. This may be necessary if
both spindles need to be synchronized for a part transfer. The
Delete CV offset
soft key enables you to reset an active angle
offset.
Additional parameters for machines with counter spindle:
CV
:
Datum shift in C axis
– active angular offset
CA : No. of C axis – Selection of C axis (main spindle or counter
spindle)
