Deceleration Stop

If the completion code is continuous, positioning returns to the target position of
sequence #0 and an immediate reversal is executed without deceleration. Then
positioning is executed for sequence #1.

When positioning is stopped by a deceleration stop, the sequence that was
stopped is re-executed by starting positioning again.

A deceleration stop with linear interpolation is executed by the Deceleration
Stop Bit of the axis where the Memory Operation Start Bit is turned ON. Actual
deceleration starts when the Deceleration Stop Execution Bit is turned ON. The
Deceleration Stop Bits of other axes become disabled and their Deceleration
Stop Execution Bits remain unchanged.
For example, when executing linear interpolation for X-axis data with the X and Y
axes, deceleration stop can only be executed by the Deceleration Stop Bit of the
X axis. When deceleration stop is executed during interpolation operation, both
the X and Y axes stop from deceleration.
When positioning is restarted, the target position will vary, as shown below,
according to whether the positions for each active axis are incremental or abso-
lute. In this example, linear interpolation is executed for the X and Y axes.
When X Axis Position is Incremental and Y Axis is Absolute
When positioning is stopped by a deceleration stop, the sequence that was
stopped can be re-executed by restarting X-axis positioning. Positioning will be
resumed for the Y axis.
