Siemens SIMATIC S7-1200 Manual page 205

The following values were configured in the "Dynamics > General" configuration window: Acceleration = 10.0 and
Deceleration = 10.0
①
An axis is moved to absolute position 1000.0 with a MC_MoveAbsolute task. When the axis reaches the target
position, this is signaled via "Done_1". When "Done_1" = TRUE, another MC_MoveAbsolute task, with target
position 1500.0, is started. Because of the response times (e.g., cycle time of user program, etc.), the axis comes
to a standstill briefly (see zoomed-in detail). When the axis reaches the new target position, this is signaled via
"Done_2".
②
An active MC_MoveAbsolute task is aborted by another MC_MoveAbsolute task. The abort is signaled via
"Abort_1". The axis is then moved at the new velocity to the new target position 1500.0. When the new target
position is reached, this is signaled via "Done_2".
