(1) Definition
The X/Y axis -direction relative position movement(ISTEP-) application command executes
a -direction relative position movement function by a designated velocity, completes the
execution of -direction relative position movement by starting a command via a rise edge
input, and outputs the completion of execution.
--- A relative position value can be designated by using a P variable or L variable
--- A movement velocity value can be designated by using an F variable or L variable.
--- When using an L variable as a relative position designation value, the designated
address is used as an X axis position value and the next address is used as a Y
axis position value.
The output is turned ON after completing the execution of a ISTEP- application command,
and is reset(OFF) during movement by another movement command.
