10.5 Spindle/C Axis Control

Precautions and Restrictions
(1) A reference position return cannot be executed by the orientation when there is no Z phase in
the detector (PLG, ENC, other).
Replace the detector with one having a Z phase, or if using the detector as it is, set the position
control changeover to "After deceleration stop" in the parameters (Spindle parameters, SP129
bitE: 1), and set the axis to "Axis without zero point" (Zero point return parameters, noref: 1).
(2) The program error (P430) will occur if a C axis command is issued during servo OFF or during
orientation.
(3) Do not execute a servo OFF during a C axis command.
The remaining C axis commands will be cleared at servo ON.
(If servo OFF is executed during C axis control, the feed will stop and spindle control will occur.)
(4) If servo ON is executed during spindle rotation, the rotation will stop and C axis control will
occur.
(5) Dog-type reference position return are not possible for the C axis.
Set the reference position return to the orientation method in the parameters (Spindle parameters,
SP129 bitE: 0), or set the axis to "Axis without zero point" (Zero point return parameters, noref:
1).
