Latch Target Block
The latch target block is a pre-
configured block that allows the
user to make use of high speed
(captures position in 30 microsec-
onds or less) without knowing the
ins and outs arming/disarming/
windowing the latch signal. The
block is much like a MOVE AXIS
block; in fact if a latch is not
received it will work identically to
a MOVE AXIS block (Default
Distance in Latch Target block =
Position in move block). How-
ever, if a Latch signal is received,
the servo will move the Distance
After Latch from the point where
the latch was detected.
Occasionally false latches can be a problem, causing the servo to move an incorrect dis-
tance. The Latch Start and Finish Distance parameters are useful in removing unwanted
latch signals. They are used to set-up a window in which the latch is expected.
