System-wide Link Types

Link Type - End of sequence

Link Type: 0 (decimal 0)

Link Value: Reserved

Range: must be 0

When this Link Type is encountered the step sequence stops: no additional steps are

executed unless they are started as a new sequence. We recommend using Step 0 as the

last Step of all chains so they all end in a known spot. If Step 0 is used this way, its link

type must be zero.

Link Type - Time Delay

Link Type: D

Link Value: Number of milliseconds to delay

Range: 0 to 65,535 milliseconds

A timer is started for this link type. When the timer reaches the value specified by the

Link Value, the next event step in the sequence is executed. Simply enter the number of

milliseconds you wish to delay in the Link Value.

Current Axis Link Types

Link Type - Current Axis Absolute Limit Switch

Link Type: L (Target Position) or l (Target Position)

Link Value: Limit Position

Range: Any valid position in position units

These link types are used to detect when the current axis crosses a position. This link

type can be used to change speeds on-the-fly or trigger events on other axes. The Link

Value holds the Limit position in position units. Either the

Target Position

or

Actual

Position

can be used to compare with the Limit position.

NOTE: The link is made once the position crosses the limit, rather than being made

whenever the position is on one side or the other of the limit. If you wish to

wait for the axis to be on one side or the other, use the

Any Axis Position

link

type.
