Independent Mode (Positioning)
Starting a Pulse Output
Note
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 triangular control
(acceleration and deceleration only.) An error will not occur.
