(Example of deceleration)
To ensure that the feedrate specified for a block is reached when the block is executed,
deceleration is started in the previous block.
To reduce feedrate F3 to feedrate F2, deceleration must be started at P1.
To reduce feedrate F2 to feedrate F1, deceleration must be started at P2.
The tool can be decelerated over several blocks, because maximum 40 blocks are read in
advance.
(Example of acceleration)
Acceleration is started to reach the specified feedrate for a block when the block is executed.
