Parameters

Parameter

Data type

Description

VAR_IN_OUT

B

Axis

AXIS_REF

Logical axis reference. This value can be located on the
Configuration tab in the Hardware Configuration (logical axis
number).

V

Buffer

CONTINUOUS_REF

Structure containing data for configuring and operating continuous
latch mode. See example below for a pictorial description of the
data.

V

Pattern

PATTERN_REF

Defines the sequence of inputs that reflect the data to be captured.

VAR_INPUT

Default

B

Enable

BOOL

The function will continue to execute while
enable is held high.

FALSE

VAR_OUTPUT

B

Valid

BOOL

Indicates that the outputs of the function are valid.

B

Done

BOOL

Set high when the commanded action has been completed
successfully. If another block takes control before the action is
completed, the Done output will not be set. This output is reset
when execute goes low.

B

Busy

BOOL

Set high upon the rising edge of the 'Execute' or 'Enable' input, and
reset if Done, CommandAborted, or Error is true.

B

Error

BOOL

Set high if error has occurred during the execution of the function
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

CONTINUOUS_REF

structure.
