G1, but it can be designated in the following
manner only when the movement reverses to the opposite direction in successive blocks. Deceleration
check can also be executed if even one axis is moving in the opposite direction while several axes are
interpolating.

G0 opposite direction movement reversal
If the axis movement reverse to the opposite direction in a G1 to G0 successive block, the deceleration
check for the movement in the opposite direction can be changed with the base specification parameter
