Case 1: When the Execute FALSE to TRUE, Busy and Active simultaneously become TRUE.
When the positioning is completed, Done becomes TRUE, and the Busy Active becomes FALSE,
if after the completion of the positioning, Execute a TRUE to FALSE, after a period, Done
becomes FALSE.
Case 2: When the Execute is TRUE, the instruction is interrupted other instructions,
CommandAborted becomes TRUE, and the Busy Active becomes FALSE; Execute when a TRUE
to FALSE, after a period CommandAborted becomes FALSE.
Case 3: During instruction execution, after the Execute TRUE to FALSE, when the
instructions are executed, the Done becomes TRUE, and the Busy Active becomes FALSE, and
after a period, the Done becomes FALSE.

Function Description

This instruction is used to set speed control shaft, deceleration and acceleration rate of
change moving distance setting, with reference to the starting point of the distance of the axis
position when the instruction to start execution.

Distance starting point with the reference axis together determine a target position under
control of the instruction, i.e. the reference target position start position = + Distance.

0 Distance When completed, the movement target position for the current position of the
axis, i.e., instruction execution in the next cycle is started, the Done becomes TRUE.
As shown below, the reference position of the starting point is 10,000, when Distance> 0
(10,000), the axis of the forward movement, the target position is 20,000 (10,000 + 10,000), in the
lower left diagram; when Distance <0 (-10000) , the reverse shaft, the target position is 0
(10000-10000), as the lower right in FIG.
