Axis Control Word 1
The functions of many of the bits in axis control word 1 depend on the
state of bit 7, which determines whether the mode of operation is auto or
manual (Figure 7.41).

Bit 0 Next Move
In the auto mode, turn on bit 0 to generate a next move command. The
next move command causes the servo positioning assembly to discontinue
executing the current move and start executing the next move.
If the endpoints for the current move and the next move are in the same
direction from the current axis position, the axis accelerates or decelerates
to the final velocity for the next move at the programmed acceleration rate
for the next move.
If the endpoint for the next move is in the opposite direction from the
endpoint of the current move, the servo positioning assembly performs a
slide stop using the decel rate programmed for the current move, then
executes the next move (bit 5, slide stop).
