This is the default mode. No buffering is performed in this mode. The current command is aborted and
the new instruction is executed. Aborting Mode can be used for multi-execution of instructions for
motion control instructions for both single-axis control and synchronized control.
 When a Reverse Turn Does Not Occur for the Command Position of the Multi-
execution Instruction
 When a Reverse Turn Occurs for the Command Position of the Multi-
execution Instruction
The buffered instruction remains in the buffer until the operation of the current instruction is finished.
The buffered instruction is executed after the operation for the current instruction is normally ended.

during Constant-velocity Motion
If you use multi-execution of an instruction during
triangular control or during deceleration, the axis will
accelerate to the target velocity of the buffered instruction.
In some cases, the axis will not reach the target velocity.

If the travel distance
upon reverse turn is
small, triangular control
is performed as it was
for the first execution of
the instruction.
↓Multi-execution timing
If the instruction is executed with multi-
execution of instructions during acceleration
or deceleration, the axis stops immediately
according to the multi-execution timing.
This also occurs during deceleration.
