Example: G720
C-angle offset G905
G905 measures the angular offset of workpiece transfer with rotating
spindle. The sum of angle C and the angle offset goes into effect as
the zero point shift of C axis. This value is saved in the variable V922
(C axis 1) or V923 (C axis 2).
The zero offset is effective internally as a direct zero point shift for the
respective C axis. The content of the variables is retained even if the
control has been switched off. The control does not initialize these
values automatically. If required, initialize the values manually by
overwriting the relevant variables.

Parameters
Q Number of the C axis
C Angle of additional zero point shift for offset gripping (–360°
<= C <= 360°) – (default: 0°)
Danger of collision!
„ For narrow workpieces the jaws have to grip at an
offset.
„ The zero point shift, C axis, remains in effect:
„ After switch from Automatic to Manual mode
„ After switch-off
