(j) The function block in the example above is as follows.
Axis1 Positioning Speed Override : When the current position of axis1 become the same position as the position
saved in %MD100, the speed value will be changed to the speed saved
in %MD92.
Axis2 Positioning Speed Override : When the current position of axis1 become 50000, the speed will be changed to
100000.
(k) For more information, reference of Position Assign Speed Override is in the “Chapter 8.5.6.”
(4) Speed/Position Switching Control
(a) This is the condition for Speed/Position Switching Control
This is the condition for Speed/Position Switching Control Command (XPM_VTP)
(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/Position Switching Control while it is running, the “error 301”
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) Signal from Speed Control by each Axis
According to exercise from “Chapter 7.1.2 Current State Reading,” it is a signal of “Speed Control state” for each axis. It
turns on when it is operating. Speed/Position Switching Control Setting can only be configured while it is running. If you
execute Speed/Position Switching Control while it is not running, the “error 302” 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) 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) For more information, reference of Speed/Position Switching Control is in the “Chapter 8.2.14.”
