(r) 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
(3) Indirect Start
(a) This is the condition for Indirect Start
This is the condition for Indirect Start Command (XPM_IST)
(b) Axis ready
If communication between the positioning module and the servo driver is normal, corresponding signal will be
on.
(c) Operating state by axis
According to exercise from “Chapter 8.2.2 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.
(d) Error state for each axis
According to exercise from “Chapter 8.2.2 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 er ror. If you want to operate a
system regardless of errors, you can just inactivate the function.
(e) Servo On signal
When applying the example program of “8.2.2 Current State Read”, this is “Servo On” signal for each axis.
When each axis is Servo On state, it will be on. Since “Indirect start” command can’t be executed when the
axis is not servo on, it makes command executed when servo driver is “Servo On” state. If you execute
“Indirect start” command when axis is not Servo On state, the error 212 occurs.
(f) Address of Positioning Module
In this example, Positioning Module is installed at the 3 slot of 0 bases.
(a) Condition for indirect start
(b) Axis ready state
(h) Step number to be ex ecuted by
indirect start
(f) Position of the module
(i) Completion state
(j) Error state
(c) Operating state
(d) Error state
(e) Servo on signal
(g) Command axis
