also change it with “real numbers,” which data type is “DINT.”
(H) Speed of Direct Start
Decide goal speed of Direct Start. In this example above, the initialized value is “device,” but you can also change it
with “real numbers,” which data type is “UDINT.”
(i) Dwell Time of Direct Start
Dwell Time consider as a total amount of time from beginning of Direct Start operation that reach to the goal position
and make output of Positioning Done Signal. That means after done its operation, direct Start will make a Positioning
done signal. Its unit is “ms,” and type is “UINT”
(j) Direct Start M code
You can set a value of M code which are displaying of Operating Parameter by Direct Start. The way of M code
outputs are “Parameter Expansion, M code Mode,” within the “None, With, After.” It will make an M code besides you
choose “None” for its parameter. For more information, reference for M code is in the “Chapter 4.2.2”
(k) Control method
Set direct start. Follows are executed depending on setting value.
0 : Position control
1 : Speed control
2 : Feed control
(l) Coordinates setting
Set the operating coordinates of direct start. Followings are executed depending on setting value.
0 : Absolute coordinates
1 : Relative coordinates
(m) Acceleration No.
Set the acc. No. used in positioning control. It operates by corresponding acc. Time of basic parameter depending on
setting value.
0 : Acc. Time 1
1 : Acc. Time 2
2 : Acc. Time 3
3 : Acc. Time 4
(n) Deceleration No.
Set the dec. No. used in positioning control. It operates by corresponding dec. Time of basic parameter depending on
setting value.
0 : Dec. Time 1
1 : Dec. Time 2
2 : Dec. Time 3
3 : Dec. Time 4
(o) State of Operation complete
If function block is completed without error, “1” will be outputted and maintain “1” until the next operation. If error
occurred, “0” will be outputted.
(p) Error State
This is the area that output error no. if there are errors in operation of function block.
(q) The function block used in the example is as follows.
Axis1 Direct Start : Execute position control with Axis1 Goal Position %MD80(axis1 Goal position), Goal
Speed %MD81(axis Goal Speed), Dwell time 100ms, M code 0, Absolute coordinates, Acc.
Time1, Dec Time 1
Axis2 Direct Start : Execute position control with Axis1 Goal Position %MD82(axis2 Goal position), Goal
Speed %MD83(axis2 Goal Speed), Dwell time 500ms, M code 0, Absolute coordinates, Acc.
Time 2, Dec Time 2
