Uwagi:
    • MC_GroupHalt is used to stop the axes group under normal operation     conditions. In non-buffered mode: during deceleration of the axes group it is     possible to set another motion command, which will abort the MC_GroupHalt and     will be executed immediately.
    • If this command is active the next command can be issued. E.g. a driverless     vehicle detects an obstacle and needs to stop. MC_GroupHalt is issued. Before     the standstill is reached the obstacle is removed and the motion can be     continued by setting another motion command, so the vehicle does not stop.
    • The relevant axes stay on the same path which would have been executed     without having issued MC_GroupHalt.
