High-Speed Oscillation
Positioning of a specified axis is caused to oscillate on a sine wave.

: Must be set,

: Set if required
*1 Only when the reference axis speed is specified
Processing details
The designated axis caused to oscillate on a specified sine wave.
Acceleration/deceleration processing is not performed.
■
Amplitude
Set the amplitude of the oscillation in the setting units.
The amplitude can be set within the range of 1 to 2147483647.
■ Starting angle
Set the angle on the sine curve at which oscillation is to start.
The setting range is 0 to 359.9 [degree]
■
Frequency
Set how many sine curve cycles occur in one minute.
The setting range is 1 to 5000 [CPM].
Since acceleration/deceleration processing is not performed, you should set the starting angle to 90 or 270
[degree] in order to avoid an abrupt start.
