[Control details]
The designated axis caused to oscillate on a specified sine wave.
Acceleration/deceleration processing is not performed.
360[degree]
Starting angle
Amplitude
(1) Amplitude
Set the amplitude of the oscillation in the setting units.
The amplitude can be set within the range of 1 to 2147483647.
(2) Starting angle
Set the angle on the sine curve at which oscillation is to start.
The setting range is 0 to 359.9 [degree]
(3) Frequency
Set how many sine curve cycles occur in one minute.
The setting range is 1 to 5000 [CPM].
POINT
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.
