Motion control instructions

MC_Stop

MC_Stop commands a controlled motion stop and transfers the axis state to

Stopping. Any ongoing function block execution is aborted. All function block

move commands are ignored until the axis state transitions to StandStill.

MC_Stop operation

As long as the Execute input is high, the axis remains in the Stopping state.

While the axis is in the Stopping state, no other motion function block can

perform any motion on the same axis.

If Deceleration equals zero, the MC_Stop function block parameters are

determined by the Axis configuration Emergency stop setting, including E-

Stop type, E-stop Deceleration and E-stop Jerk.

The axis goes to StandStill after the Done bit is SET and the Execute input

is changed to False if there is no error detected during the stop sequence.

The MC_Stop function block is primarily intended for emergency stop

functionality or exception situations. For normal motion stop, MC_Halt

function block is usually used.
