8.2.6 Positioning Operation
(1) Homing
(a) This is the condition for Homing
This is the condition for Homing Command (XPM_ORG)
(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. Homing command can not be configured while it is running hence configuration
will only be configured when it is not running. If you execute Homing while it is running, the “error 201” 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 er ror 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 “Home return” 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 “Home
return” command when axis is not Servo On state, the error 203 occurs.
(f) Address of Positioning Module
In this example, Positioning Module is installed at the 3 slot of 0 bases.
(g) Axis of command execution
You can set an axis for Inching Operation. XBF-PN04(8)B supports for 4(8) axes. In the “execution of axis”
from the configuration of Manual Operation, you can set a value for axis1 through axis4(8).
(h) State of Operation complete
If function block is completed without error, “1” will be outputted and m aintain “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) For more information, reference for Homing is in the “Chapter 9.1.”
(a) Condition for home return
(b) Axis ready state
(c) Operating state
(d) Error state
(e) Servo on signal
(f) Position of the module
(h) Completion state
(g) Command axis
(i) Error state
