J{data}

Function:

J-Vector Specification for Circular Moves

Type:

Motion program (PROG and ROT)

Syntax:

J{data}

where:



{data} is a floating-point constant or expression representing the magnitude of the J-component of
the vector in scaled user axis units.

In circular moves, this specifies the component of the vector to the arc center that is parallel to the Y-axis.
The starting point of the vector is either the move start point (for INC (R) mode – default) or the XYZ-
origin (for ABS (R) mode).

In a NORMAL command, this specifies the component of the normal vector to the plane of circular
interpolation and tool radius compensation that is parallel to the Y-axis.

Examples:

X10 Y20 I5 J5
Y(2*P1) J(P1)
J33.333

; Specifies a full circle whose center is 33.333 units in the positive

; Y-direction from the start and end point

NORMAL J-1

; Specifies a vector normal to the ZX plane
