12-11-2 Positioning Control (Independent Mode)
* Triangular Control
If the specified number of pulses is less than the number required just to reach the target frequency and
return to zero, the function will automatically reduce the acceleration/deceleration time and perform triangu-
lar control (acceleration and deceleration only.) An error will not occur.
