Trajectory Profile Generation
The trajectory profile generator performs calculations to determne the
target position, velocity and acceleration at each servo loop. These
calculations are performed using the current profile mode and profile
parameters set by the host. Four trajectory profile modes are supported:
- S-curve point to point
- Trapezoidal point to point
- Velocity contouring
- Electronic Gear
The commands to select these profile modes are
SET_PRFL_S_CRV (to select the s-curve mode), SET_PRFL_TRAP
(to select the trapezoidal mode) SET_PRFL_VEL (to select the
velocity contouring mode) and SET_PRFL_GEAR (to select the
electronic gear mod).
Throughout this manual various command mnemonics will be
shown to clarify chipset usage or provide specific examples. See
the Host Communications section for a description of host
command nomenclature.
