AXIS_STOP
Commanded controlled stop that decelerates the axis at a set rate, proves standstill from feedback, and holds the axis against other motion commands.
When to use it
Use AXIS_STOP when a sequence, an interlock or an operator has to bring an axis to a controlled halt at a known deceleration and then hold it there so no other motion block can take it until the hold is deliberately released.

Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML and the datasheet.
Every block in the catalogue is free to download, in every format it ships, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
