can use Y0.
When Y0 is used:
Y0 refers to the X-axis pulse outputs.
Y1 refers to the X-axis direction signal.
Y2 refers to the Y-axis pulse outputs.
Y3 refers to the Y-axis direction signal.
6. Draw four 90
°
arcs. When the direction signal is Off, the direction is positive. When the direction
signal is On, the direction is negative. When S is set as K0, the arcs will be clockwise (see figure
5). When S is set as K1, the arcs will be counterclockwise (see figure 6).
7. When the 2-axis motion is being executed, the operation time of the instruction when the
instruction is first enabled is approximately 2ms.
8. Each time the instruction is executed, only one 90
°
arc can be drawn.
9. There are no settings for the start frequency and acceleration/deceleration time.
10. There is no limit on the number of times this instruction can be used in the program.
11. The settings for the direction and resolution are in the lower 16 bits of
S
and can only be K0 ~
K1.
12. The settings for the motion time are in the high 16 bits of S and can be slower than the fastest
suggested time but shall not be faster than the fastest suggested time.
13. The fastest suggested time for the arc interpolation:
