13 Spindle Control
13.13 Spindle Oscillation
(*1) This represents whether function commands are allowed/not allowed while spindle oscillation is in operation. If a com-
mand for a function that is not allowed is output while spindle oscillation is in operation, the operation error (M01 1108) is
generated.
(*2) This represents whether the spindle oscillation command is allowed/not allowed while another function is executing. If
the spindle oscillation command is output while a function that is not allowed is executing, the operation error (M01
1109) is generated.
(*3) The command can be output, but the function will not operate while spindle oscillation is in operation. The spindle will
start rotating at the specified speed after spindle oscillation completes.
(*4) The command can be output, but the function will not operate while spindle synchronization is in operation. Spindle
oscillation will start after the spindle stops rotating.
(*5) The command can be output, but the spindle continues to oscillate while the control related to rotational speed of the
function command subsequently output is ignored as the spindle oscillation function causes the spindle to oscillate at a
rotational speed calculated from the configured amplitude and frequency.
(*6) The command can be output, but the spindle oscillates while the control related to rotational speed of the function com-
mand previously output is ignored as the spindle oscillation function causes the spindle to oscillate at a rotational speed
calculated from the configured amplitude and frequency.
(*7) If the spindle oscillation command is output while the tapping retract enable signal (TRVE: XCA5) is turned ON, the oper-
ation error (M01 1109) is generated.
(*8) The command can be output, but spindle synchronization continues.

13.13.4 Precautions

(1) The zero speed signal (ZSO: X188C) and spindle speed arrival signal (USO: X188D) may turn ON due to oscillation of
the spindle. The spindle forward movement signal (SSRN: X1893) and spindle reverse movement signal (SSRI: X1894)
repeatedly turn ON and OFF while the spindle oscillates.
(2) Spindle oscillation does not stop when an NC reset is performed while the spindle is oscillating. To stop oscillation, you
must turn OFF the spindle oscillation command signal by performing a reset.
(3) The spindle stops when an emergency stop is performed while the spindle is oscillating. Spindle oscillation will not restart
after the emergency stop is cleared.
