_8134_set_sd_stop_mode (ByVal axis As Integer, ByVal stopmode
As Integer) As Integer
@ Argument
axis: axis number designated to move or stop.
str_vel: starting velocity in unit of pulse per second
max_vel: maximum velocity in unit of pulse per second
Tacc: specified acceleration time in unit of second
Tdec: specified deceleration time in unit of second
Tlacc: specified linear acceleration time of S-
curve in unit of second
Tsacc: specified S-curve acceleration time of S-
curve in unit of second
stopmode: 0=slow down to starting velocity, 1=slow
down then stop
*minAccT: calculated minimum acceleration time
*maxAccT:
calculated maximum acceleration time
MaxSpeed: The value of maximum speed setting in
motion function or in fix_max_speed function
@ Return Code
ERR_NoError
The return value of verify_speed is the calculated starting velocity
