8-84
(e) Servo error information
It specifies the device to save “servo error information” read by “XPM_SVERD”. You can use this device as
execution condition in the sequence program. In the above example, current servo error information of axis 1 is
saved in the device “%MW303”.
(f) 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.
(g) Error State
This is the area that output error no. if there are errors in operation of function block.
(5) Reading Servo Input Information (XPM_SVIRD)
(a) Module’s ready
After Turn On, if there is no error occurred in Positioning Module, it is “ON,” meaning that modules are ready to
operate.
(b) Axis ready
If communication between the positioning module and the servo driver is normal, corresponding signal will be
on. In the example program, since _ON (Always ON), positioning module ready (UX0.3.15) and axis ready
(UX0.3.0 ~ UX.3.1) are used, if there is no error in the module, it reads the current status every scan.
(c) Address of Positioning Module
Before operation, you need t o configure its position by numbers. In this example, Positioning Module is
installed at the 3 slot.
(d) Axis of operation
If you command each axis, need to set Axis of command execution. XBF-PN04(8)B can control max. 4(8) axes
and Axis of command execution 1~4(8) means axis1~axis4(8).
(e) Servo input information
It sets the device to save input signal information of the each axis from positioning module by using
XPM_SVIRD. This device can be used as a condition in sequence program. For example above, servo input
signal information of 1-axis is saved at %MD400.
(f) 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.
(g) Error State
This is the area that output error no. if there are errors in operation of function block.
