7.1.6 Operation Setting Change while Operating
(1) Speed Override
(a) This is the condition for Speed Override
This is the condition for Speed Override Command (XPM_SOR)
(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 Speed Override while it is running, the “error 371” 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) Address of Positioning Module
In this example, Positioning Module is fixed at the 1 slot of 0 bases.
(e) 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.
(f) Value Change for Speed Operation
Set speed value. According to Speed Override from common parameters, it is a signal of “%” or “Speed Value”
depends on setting of category. Also, when Speed Override set as Speed Value, it means Unit/Time depends on
Speed Command Unit from basic parameters, or it means “rpm.” If a changing Operation Speed Value is “%,” then the
unit would be [X10
-2
%]. If it is “rpm, “then the unit would be X10
-1
rpm].
(g) 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.
(h) Error State
This is the area that output error no. if there are errors in operation of function block.
(i) The function block in the example above is as follows.
Axis1 Speed Override : The operating speed of axis1 will be changed to speed value saved in %MD97 and then
continue to operate.
Axis2 Speed Override : The operating speed of axis2 will be changed to 20000 and then continue to operate.
(j) For more information, reference of Speed Override is in the “Chapter 8.5.5.”
