Input type
ICW <P variable 1> <P variable 2> , ICCW <P variable 1> <P variable 2>
Terminology
<P variable>: Set the variable for a position from the Position Table.(P0 ~ P99)

variable
P variable, L variable

command
A,D,VEL
Parameter
Maximum velocity(P18), acceleration or deceleration time(P23), deceleration time(P65), I, J arc
commanding method(P61)
Explanation
Move by arc interpolation from the current position to the commanded incremented position at the
commanded velocity and Acceleration or deceleration time.
If the“
basic
parameter
P61 I, J arc commanding method” is disabled, then the X-axis value of <P
variable 2> is regarded as its radius.
However, if the “
basic
parameter
P61 I, J arc commanding method” is enabled, then it is
regarded as an I, J circle center commanding method, not a radius. In this case, the X-axis of the
second P variable corresponds to I, and the Y-axis corresponds to J.
I, J are vector components seen from the arc start point to the center, and are always commanded as
increments.
