(3) Indirect Start
(a) This is the condition for Indirect Start
This is the condition for Indirect Start Command (XPM_IST)
(b) Operating state by axis
According to exercise from “Chapter 7.1.2 Current State Reading,” it is a signal of “Operating” for each axis. It turns on
when it is operating. Operating Data Setting can not be configured while it is running hence configuration will only be
configured when it is not running. If you execute Indirect Start while it is running, the “error 231” would be appeared.
(c) Error state for each axis
According to exercise from “Chapter 7.1.2 Current State Reading,” it is a signal of “Error state” for each axis. It turns on
when an error occurred. Operation will only work when there is no error. If you want to operate a system regardless of
errors, you can just inactivate the function.
(d) Ready signal for each axis
According to exercise from “Chapter 7.1.2 Current State Reading,” it is a signal of “Drive Ready” for each axis. This
command only works when this is the condition for Drive Ready is on. If it is not set as “ON,” the “error 235” would be
appeared.
(e) Address of Positioning Module
In this example, Positioning Module is fixed at the 1 slot of 0 bases.
(f) Axis of command execution
You can set an axis for Parameter Setting. UP type supports for 4 axes. In the “execution of axis” from the
configuration of Parameter Setting, you can set a value for axis1 through axis4.
(g) Operating step number by Indirect Start
Set the operating step number by indirect start for main Axis of command execution.
(h) 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.
(i) Error State
This is the area that output error no. if there are errors in operation of function block.
(j) Indirect start operates by appointing step of position data for each axis. Therefore it could run those commands of
Positioning control, Speed control, Feed control, Linear circular interpolation depends on setting of positioning data. For
more information, reference for Setting of Operating Data is in the “Chapter4.8.”
(k) The operation of function block is as follows.
Axis1 Indirect Start : Execute step no.1 of axis1 by indirect start
Axis2 Indirect Start : Execute %MW168(Indirect start step) of axis2 by indirect start
