Operation Theorem

If this ratio is not set before issuing the start moving command, it will cause
problems when running in “Absolute Mode”. Because the PPCI7443 can’t
recognize the actual absolute position during motion.

Relative Functions:

_7443_start_ta_move(),_7443_start_tr_move() : Refer to section 6.6
_7443_motion_done(): Refer to section 6.11
_7443_set_feedback_src(): Refer to section 6.4
_7443_set_move_ratio(): Refer to section 6.6

4.1.4

S-curve Motion Profile

This mode is used to move one axis motor to a specified position (or
distance) with a S-curve velocity profile. S-curve acceleration profiles are
useful for both stepper and servo motors. The smooth transitions between
the start of the acceleration ramp and the transition to the constant velocity
produce less wear and tear than a trapezoidal profile motion. The smoother
performance increases the life of the motors and mechanics of a system.

There are several parameters needed to be set in order to make a S-curve
move. They are:

Pos:

target position in absolute mode, in unit of pulse.

Dist :

moving distance in relative mode, in unit of pulse.

StrVel: specify the start velocity, in unit of PPS.
MaxVel: specify the maximum velocity, in unit of PPS.

Tacc pecify the time for acceleration (StrVel

MaxVel), in unit of

second.

Tdec:

specify the time for deceleration (MaxVel

StrVel), in unit of

second.

SVacc : specify the S-curve region during acceleration, in unit of PPS.
SVdec : specify the S-curve region during deceleration, in unit of PPS.
