Moving distance
S1
When M0 = “ON”, as the diagram above, the Y0 by the set operating speed to generate the corresponding
number of pulses. That pulse number comes from the set value of moving distance . When the number of the
moving distance is nished, it stops to generate pulses, the positioning action is completed.
Assume that the rotational mode “Increase present value when forward” is selected. If the set value of the moving
distance is a positive number, that needs to increase the present value, thus the instruction will turn the Y4
“ON” to drive motor moves forward. On the other hand, the set value of the moving distance is a negative number,
that needs to decrease the present value, thus the instruction will turn the Y4 “OFF” to drive motor moves backward.

is for to assign the moving distance.
If the > 0, it will move in the direction of to increase the present value. Oppositely, if the < 0, it will
move in the direction of to decrease the present value. The PLC will convert this distance to the pulse unit for
the positioning, thus the converted number must meet the range of a 32-bit data. If the converted value is
exceeded, the PLC will be regarded that as an operating error and M9067 will be “ON”.
is for to assign the output point of direction control signal.
When the output of direction control signal is “ON”, the motor moves forward; conversely, “OFF” moves
reverse.
Besides, the “ON”/“OFF” status of the direction control signal is decided by both the +/– numerical value of
the distance and the parameter of the rotational direction (increase present value when forward /
backward) are executed.

is for to assign the operating speed.
The available range is from the bias speed (D9342) to the maximum speed (D9341, D9340).
When < the bias speed, it will be regarded as the bias speed; when > the maximum speed, it will be
regarded as the maximum speed.
is for to assign the output point of generated pulse string.
It can only appoint to a point between Y0~Y3, and must use a transistor or line driver output Main Unit.
