StrVel item: Starting velocity. API function's argument variable “StrVel”.
MaxVel item: Maximum velocity. API function's argument variable “MaxVel”.
Acc. item: Time required to reach maximum velocity. API function's argument
variable “acc”.
Dec item: Time required to go from maximum velocity to 0. API function's argument
variable “dec”.
Abs. Checkbox: You must check this if you want motion displacement to use
absolute coordinates.
S-Curve checkbox: You must check this box if you wish to use the S-curve velocity
curve.
4) Select the type of 2-axis arc interpolation and enter the corresponding values
Figure 3.51
Arc 1: Interpolation method 1. Must provide the center coordinates (X, Y) and angle
(0
o to 359 o )
➊ Cen_X item: Center's x-coordinate. API function's argument variable
“arc1_cen_x”.
Cen_Y
item: Center's y-coordinate. API function's argument variable
“arc1_cen_y”.
Angle item: Angle. API function's argument variable “arc1_angle”.
Arc 2: Interpolation method 2. Must enter the endpoint coordinates (X, Y) and angle
(0
o to 359 o )
➋ End_X item: Endpoint's x-coordinate. API function's argument variable
“arc2_end_x”.
End_Y item: Endpoint's Y-coordinate. API function's argument variable
“arc2_end_y”.
Angle item: Angle. API function's argument variable “arc2_angle”.
Arc 3: Interpolation method 3. Must provide the center coordinates (X, Y), endpoint
coordinates (X, Y) and direction.
