MC_Stop_SML (FB)¶

FUNCTION_BLOCK MC_Stop_SML

Executes a (blocking) stop on the axis.

As long as the Execute input is set or the stop is not finished, no other motion command is possible on the axis, and the axis state is Stopping. After both the stop is finished and Execute is reset, the axis status is set to Standstill.

This diagram illustrates the behavior of MC_Stop_SML:

The example below shows the behavior in combination with MC_MoveVelocity_SML.

1. A rotating axis is ramped down with FB MC_Stop_SML.

2. The axis rejects motion commands as long as MC_Stop_SML parameter Execute = TRUE. MC_MoveVelocity_SML reports an error indicating the busy MC_Stop_SML command.
