Parameter
Data type
Description
VAR_IN_OUT
B
Axis
Logical axis reference. This value can be located on the
Configuration tab in the Hardware Configuration (logical axis
number).
V
Buffer
Structure containing data for configuring and operating continuous
latch mode. See example below for a pictorial description of the
data.
V
Pattern
Defines the sequence of inputs that reflect the data to be captured.

block. This output is cleared when 'Execute' or 'Enable' goes low.
E
ErrorID
UINT
If error is true, this output provides the Error ID. This output is reset
when 'Execute' or 'Enable' goes low.
Notes
Controller firmware version 1.2.4.6 or higher is required to use this
function block. This function block is located in the YMotion firmware
library.
The physical hardware in the Sigma-5 servo amplifier can only store one
latch at a time. However, the controller can store many of them into the
