Position - Time (PT)

In a PT motion, the user specifies a sequence of absolute positions with equal time spaces
to be visited by the drive. The time space must be an integer multiple of the drive
sampling time. Between the user-specified positions, the drive interpolates smooth
motion. The position specifications are absolute.
