Machine Data, Modes and Traversing Programs
The table below lists the permissible functions in absolute increment mode for
both rotary and linear axes.

Function
START Approach to target over the shortest
possible path
STOP Exit mode
FORWARD Approach to target in forward direc-
tion (clockwise). If the axis is already at
the target position, the entire range is
traversed once.
REVERSE Approach to target in reverse direction
(counter-clockwise). If the axis is al-
ready at the target position, the entire
range is traversed once.
EXEC Change the speed via the Override factor when the axis is "traversing".
