(14) Reset Latch
(a) Condition for Reset Latch
(b) Axis ready state
(d) Position of the module
(e) Command axis
(g) Completion state
(h) Error state
(c) Latch completion state
(f) Reset latch item
(a) This is the condition for Reset Latch
This is the condition for Reset Latch Command (XPM_LCLR). Once Reset Latch is executed, it reset state of
latch completion or latch data by set the reset latch item.
(b) Axis ready
If communication between the positioning module and the servo driver is normal, corresponding signal will be
on.
(c) Latch completion state
It is the state of “Latch Completion” when an example program of“8.2.2 Read the Current Sate.” It is on when
latch is completed once external latch command signal of the relevant axis is inputted. In case of Axis 2, the
Reset latch item is executed as soon as %MB4.6 (Latch Completion state) is On. To read latch data every
time when latch is completed upon the input of the axis’s external latch command signal, program to set latch
completion as a c ondition for the Reset Latch command after executing the Read Latch Location Data
command.
(d) Address of Positioning Module
In this example, Positioning Module is installed at the 3 slot of 0 bases.
(e) Axis of command execution
You can set an axis for Reset Latch. XBF-PN04(8)B supports for 4(8) axes. In the “execution of axis” from the
configuration of Reset Latch, you can set a value for axis1 through axis4(8).
