13 Spindle Control
13.13 Spindle Oscillation
When the rotational speed of the spindle calculated from the amplitude and frequency exceeds the maximum rotational speed
spindle parameters ("#3005 smax1 Maximum Rotational Speed (gear: 00)" through ("#3008 smax4 Maximum Rotational
Speed (gear: 11)"), the spindle cannot oscillate at the configured frequency, which results in generation of the operation error
(M01 1110).
If the amplitude and frequency setting is too small, this results in a calculated command value of less than one pulse being
output to the spindle amp, which results in generation of the operation error (M01 1110).
As the spindle oscillates in accordance with the configured amplitude and frequency when the spindle oscillation start
command is received, the amplitude and frequency of currently executing oscillation does not change when the amplitude and
frequency settings change while the spindle is oscillating. To oscillate the spindle at the changed amplitude and frequency,
turn the spindle oscillation command signal OFF and ON again.
The starting and stopping of the spindle oscillation is performed with the spindle oscillation command signal level trigger. If
spindle oscillation cannot start due to the execution of other functions, spindle oscillation starts after the other function
completes.

To restart spindle oscillation when an oscillating spindle has stopped due to an emergency stop or the generation of a spindle
alarm, turn the spindle oscillation command signal OFF and ON again.

is not possible"
Stop at orientation position
"After orientation is canceled
