@ Description
General
:
The moving direction is determined by the sign of the Pos or
Dist parameter. If the moving distance is too short to reach the
specified velocity, the controller will automatically lower the
MaxVel
, and the
Tacc
,
Tdec
,
VSacc
, and
VSdec
will also
become shorter while dV/dt(acceleration / deceleration) and
d(dV/dt)/dt (jerk) are keep unchanged.
_8154_start_tr_move
:
This function causes the axis to accelerate form a starting
velocity (StrVel), rotate at constant velocity (MaxVel), and
decelerate to stop at the
relative
distance
with
trapezoidal
profile. The acceleration (Tacc) and deceleration (Tdec) time is
specified independently–it does not let the program wait for
motion completion but immediately returns control to the pro-
gram.
